  • Links

    Links are used to navigate from one webpage to other with a single click. We can use CSS properties to style links in various ways.

    CSS Links Example

    We can create a link in webpage using <a> tag. With CSS we can style this to built text link, button link and image link as shown below.

    • CSS Button Links
    • CSS Image Links

    A link in a webpage exist in various states, and these states of link can be styled using pseudo-classes in CSS. Following are common states of link.

    • Link: Represents unvisited links. This state of links can be styled with :link pseudo class. (This is default state for anchor tag).
    • Visited: Represents the links that are already visited (present in browser’s history). This state of links can be styled with :visited pseudo class.
    • Hover: Represents the state when user hover’s the mouse pointer over link. This state of links can be styled with :hover pseudo class.
    • Active: Represents the state when user clicks the link. This state of links can be styled with :active pseudo class.

    Following are default styles applied to a link in webpage. You can modify this style using CSS.

    • All the links will be underlined. You can remove this by setting text-decoration property to ‘none’.
    • All the unvisited links will be in blue color and visited links will be purple. You can use color property to modify this
    • The mouse pointer changes to a little hand icon when you hover over a link. You can use cursor property to modify this.
    • Hovered links will be underlined and active links are styled in red.

    A text content when clicked will navigate to a different webpage or a section of same page is called text link. Following example show how to make a text link.

    Example

    <html><head><style>
    
        body{
            padding: 10px;
        }
        a {
            color: blue; 
            text-decoration: none; 
        }
        a:hover {
            text-decoration: underline;
            transform: scale(1.1);   
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;a href="/index.htm"&gt; Click Me &lt;/a&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    As mentioned above in this example we have used pseudo-classes to style different states of a link.

    Example

    <html><head><style>
    
        body {
            padding: 10px;
            font-size: 1.2rem;
            font-family: sans-serif;
        }
        a {
            display: inline-block;
            transition: transform 0.2s ease;
        }
        a:link {
            color: green; 
            text-decoration: none;
        }
        a:visited {
            color: purple; 
        }
        a:hover {
            text-decoration: underline;
            transform: scale(1.1)
        }
        a:active {
            color: black;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;p&gt; Select course &lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;a href="/html/index.htm" target="_blank"&gt; 
            HTML 
        &lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="/css/index.htm" target="_blank"&gt; 
            CSS 
        &lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href="/python/index.htm" target="_blank"&gt; 
            Python 
        &lt;/a&gt;&lt;/li&gt;&lt;/ul&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    In CSS we can styles links in such a way that it looks like a clickable button. Following example shows this.

    Example

    <html><head><style>
    
        body {
            display: flex;
            justify-content: space-around;
            padding: 10px;
            height: 100px;
        }
        .button {
            display: inline-block;
            color: white;
            background-color: blue;
            height: 20%;
            padding: 10px 20px;
            text-align: center;
            text-decoration: none;
            border-radius: 5px;
            transition: all 0.3s ease;
        }
        .button:hover {
            background-color: darkblue;
            transform: scale(1.1);
            box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;a class="button" href="/css/index.htm" target="_blank" &gt; 
        CSS
    &lt;/a&gt;&lt;a class="button" href="/html/index.htm" target="_blank" &gt; 
        HTML 
    &lt;/a&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    We can also attach links on images displayed in webpage. Following example shows this.

    Example

    <html><head><style>
    
        body {
            display: flex;
            justify-content: space-around;
            padding: 10px;
            height: 100px;
        }
        a img {
            transition: all 0.3s ease;
            border-radius: 5px;
        }
    
        a:hover img {
            transform: scale(1.05);
            box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;a href="/css/index.htm" target="_blank" &gt;&lt;img src="/css/images/css.png" 
              alt="css-image-link" height="60px" &gt;&lt;/a&gt;&lt;/body&gt;&lt;/html&gt;</pre>

  • Images

    In this article, we will learn about how to style an image to change its shape, size, and layout by using different CSS properties such as padding, borders, height, width, margins, etc.

    Table of Contents

    • Round Cornered Images
    • Circular And Elliptical Images
    • Bordered Images
    • Image Filters
    • Image as a Card
    • Center an Image
    • Text Inside Image
    • Image Fade In Overlay

    Round Cornered Images

    The following example demonstrates how to use border-radius property to create rounded border image.

    Example

    <!DOCTYPE html><html><head><style>
    
        img {
            width: 100px;
            height: 100px;
            border-radius: 20px;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;img src="/css/images/pink-flower.jpg" alt="pink-flower"&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Circular And Elliptical Images

    The following example demonstrates how to use border-radius: 50% property to create images in circle and ellipse shape. When height and width of image are same we will get a circular image and when they are not same we will get elliptical images.

    Example

    <!DOCTYPE html><html><head><style>
    
        img {
            width: 100px;
            height: 100px;
            border-radius: 50%;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;img src="/css/images/pink-flower.jpg" alt="pink-flower"&gt;&lt;img src="/css/images/pink-flower.jpg" 
         style="height: 50px" alt="pink-flower"&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Bordered Images

    The following example demonstrates how to create a border around any images.

    Example

    <!DOCTYPE html><html><head><style>
    
        img {
            border: 2px solid red;
            border-radius: 10px;
            border: 7px solid black;
            width: 150px;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;img src="/css/images/pink-flower.jpg" alt="pink-flower"&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Image Filters

    The following example demonstrates that different filter effects are applied to an image using filter property.

    Example

    <!DOCTYPE html><html><head><style>
    
        img {
            width: auto;
            height: 50px;
            margin: 10px;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h4&gt;Blur Filter&lt;/h4&gt;&lt;img style="filter: blur(3px);" src="/css/images/pink-flower.jpg"&gt;&lt;h4&gt;Invert Filter&lt;/h4&gt;&lt;img style="filter: invert(110%);" src="/css/images/pink-flower.jpg"&gt;&lt;h4&gt;Saturate Filter&lt;/h4&gt;&lt;img style="filter: saturate(8);" src="/css/images/pink-flower.jpg"&gt;&lt;h4&gt;Sepia Filter&lt;/h4&gt;&lt;img style="filter: sepia(110%);" src="/css/images/pink-flower.jpg"&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Image as a Card

    The following example demonstrates a responsive polaroid-styled image with a shadow effect.

    <!DOCTYPE html><html><head><style>
    
        .polaroid-image {
            width: 60%;
            height: 200px;
            background-color: white;
            box-shadow: 0 3px 6px 0 grey, 0 8px 16px 0 black;
            margin-bottom: 25px;
            margin: 20px;
        }
        img {
            width: 100%;
            height: 150px;
        }
        .box {
            text-align: center;
            padding: 5px;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;div class="polaroid-image"&gt;&lt;img src="/css/images/red-flower.jpg" alt="Flower"&gt;&lt;div class="box"&gt;&lt;p&gt;Tree&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Center an Image

    There are several way to center an image inside a container, most popular way is to use flex layout with justify-content and align-items properties.

    • justify-content: center: This will center image horizontally
    • align-items: center: This will center image vertically

    Example

    In this example we used flex layout to center an image

    <!DOCTYPE html><html lang="en"><head><style>
    
        .container {
            display: flex;          
            justify-content: center; 
            align-items: center;    
            height: 300px;           
            border: 2px solid black; 
        }
        img {
            max-width: 100%;        
            height: auto;         
            border: 1px solid;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;div class="container"&gt;&lt;img src="/css/images/logo.png"&gt;&lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Text Inside Image

    In CSS position property can be used to position text in different locations inside an image.

    First we need to set position property for image container as position: relative and position property of text as position: absolute. Now you can position of text elements using inset properties like top, bottom, right and left.

    Example

    <!DOCTYPE html><html><head><style>
    
        .container {
            position: relative;
            border: 2px solid #ef2c2c;
        }
        .center {
            position: absolute;
            top: 45%;
            width: 100%;
            text-align: center;
        }
        .top-left {
            position: absolute;
            top: 12px;
            left: 30px;
        }
        .top-right {
            position: absolute;
            top: 12px;
            right: 30px;
        }
        .bottom-left {
            position: absolute;
            bottom: 12px;
            left: 30px;
        }
        .bottom-right {
            position: absolute;
            bottom: 12px;
            right: 30px;
        }
        img {
            width: 100%;
            opacity: 0.7;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;div class="container"&gt;&lt;img src="/css/images/red-flower.jpg" 
                width="1000px" height="350px"&gt;&lt;h3 class="center"&gt;
            Text at Center
        &lt;/h3&gt;&lt;h3 class="top-left"&gt;
            Text at Top Left
        &lt;/h3&gt;&lt;h3 class="top-right"&gt;
            Text at Top Right
        &lt;/h3&gt;&lt;h3 class="bottom-left"&gt;
            Text at Bottom Left&lt;/h3&gt;&lt;h3 class="bottom-right"&gt;
            Text at Bottom Right
        &lt;/h3&gt;&lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Image Fade In Overlay

    Fade in overlay effect shows text when you hover over the image. There are several other overlay effects, for complete understanding checkout our tutorial on CSS overlay effects.

    Let's look at an example for image fade in overlay effect.

    Example

    <!DOCTYPE html><html><head><style>
    
        .img-container {
                position: relative;
                width: 250px; 
        }
        .img-overlay {
            position: absolute;
            top: 0;
            left: 0;
            width: 100%;
            height: 100%;
            background: rgba(0, 0, 0, 0.7); 
            opacity: 0;
            transition: opacity 0.4s ease; 
        }
        .overlay-text {
            color: red;
            font-weight: bold;
            font-size: 25px;
            position: absolute;
            top: 40%;
            left: 20%;
        }
        .img-container:hover .img-overlay {
            opacity: 1;
        }
        img {
            width: 100%;
            height: 200px;
            display: block;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;div class="img-container"&gt;&lt;div class="img-overlay"&gt;&lt;div class="overlay-text"&gt;TutorialsPoint&lt;/div&gt;&lt;/div&gt;&lt;img src="/css/images/see.jpg" alt="See Image"&gt;&lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

  • Styling Text

    CSS Styling Text involves modifying the appearance of text content by setting proper color, alignment, letter-spacing, and indention to make it more visually appealing. This chapter demonstrates how to style texts on web pages using CSS properties.

    How to Style Text in CSS?

    We can style text in the following ways to style texts in CSS.

    • Change Color: The default color of text on a webpage will be black. You can change this according to your webpage theme, using the color property in CSS.
    • Set Alignment: You can use the text-align property in CSS to specify the alignment (center, left, right) of text inside a container.
    • Text Decoration: The text-decoration property in CSS can be used to add effects like underline, overline, or strike-through to texts.
    • Shadow Effect: If you want to create a shadow around text in your webpage you can use text-shadow property in CSS. This can create a 3D effect or a subtle glow around the text.
    • Change Font Style: The font-style property allows you to style the text as normal, italic, or oblique.

    Setting Text Color in CSS

    To set the text color, you can use the color property. The color can be specified with color name, Hexadecimal value, rgb/rgba value, or hsl/hsla value.

    Example

    In this example, we have set the text color of paragraphs using the color property.

    <!DOCTYPE html><html><head><style>
    
        .name {
            color: blueviolet;
        }
        .hex {
            color:#ff00ff;
        }
        .rgb {
            color: rgb(255,124,100);
        }
        .rgba {
            color: rgb(255,124,100,0.5);
        }
        .hsl {
            color: hsl(7deg, 98%, 50%);
        }
        .hsla {
            color: hsl(7deg, 98%, 50%, 0.5);
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;p class="name"&gt;
        Color Name: blueviolet;
    &lt;/p&gt;&lt;p class="hex"&gt;
        Hexadecimal value: #ff00ff;
    &lt;/p&gt;&lt;p class="rgb"&gt;
        RGB value: rgb(255, 124, 100);
    &lt;/p&gt;&lt;p class="rgba"&gt;
        RGBA value: rgba(255, 124, 100, 0.5);
    &lt;/p&gt;&lt;p class="hsl"&gt;
        HSL value: hsla(7deg, 98%, 50%);
    &lt;/p&gt;&lt;p class="hsla"&gt;
        HSLA value: hsla(7deg, 98%, 50%, 0.5);
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Setting Text Alignment

    The text in a webpage can be aligned horizontally and vertically inside a container. To set the alignment of the text, we use the following CSS properties.

    • The text-align property specifies the horizontal alignment of text in a container (left, right, center, justify).
    • The vertical-align property is used to align the text vertically at the top, bottom, baseline, and middle. This property is used with inline elements, inline-block elements, and table cells.

    Example

    In this example, we have used text-align and vertical-align properties to set the horizontal and vertical alignment of the text.

    <!DOCTYPE html><html><head><style>
    
        th{
            vertical-align: bottom;
            border: 2px solid; 
            width: 200px; 
            height: 150px;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;Text Alignment&lt;/h2&gt;&lt;p style="text-align: left;"&gt;Text Left Alignment.&lt;/p&gt;&lt;p style="text-align: right;"&gt;Text Right Alignment.&lt;/p&gt;&lt;p style="text-align: center;"&gt;Text Center Alignment.&lt;/p&gt;&lt;table&gt;&lt;th&gt;This is vertical alignment&lt;/th&gt;&lt;/table&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    To set the alignment for the last line of a block of text, you can use the text-align-last property. It is useful when text-align: justify; is used to align the last line properly.

    Example

    In this example, we have used the text-align-last property to align the last line differently.

    <!DOCTYPE html><html><head><style>
    
        p {
            width: 300px;
            text-align: justify;
            text-align-last: right;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;text-align-last property&lt;/h2&gt;&lt;p&gt;This is an example of text alignment. The last line of this paragraph will be aligned differently than the rest of the text.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Aligning Text with text-justify

    The text-justify property specifies the justification method of text when text-align: justify; is applied. The text remains unaffected in modern browsers. Try running the code in Firefox.

    Example

    In this example, we have used the text-justify property to control text justification.

    <!DOCTYPE html><html><head><style>
    
        p {
            width: 300px;
            text-align: justify;
            text-justify: inter-word;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;text-justify property&lt;/h2&gt;&lt;p&gt;This paragraph demonstrates how the text-justify property works. It adjusts the spacing between words.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Setting Text Direction in CSS

    The text direction refers to the orientation of text characters in a document or element. You can use the direction property to set the text direction. This property accepts two values which are as follows:

    • ltr (Left-to-Right): It is the default value, used for languages that are written from left to right, like English.
    • rtl (Right-to-Left): It is used for languages that are written from right to left, such as Arabic or Hebrew. When using rtl, the text will be aligned right by default.

    Additionally, CSS provides a shorthand property, unicode-bidi, to control the bidi algorithm, which specifies how characters with different writing directions are displayed when they appear in the same paragraph.

    Example

    In this example, we have used the direction property to set the text direction of paragraphs.

    <!DOCTYPE html><html><body><p style = "direction: rtl;">
    
        Right to Left
    &lt;/p&gt;&lt;p style = "direction: ltr;"&gt;
        Left to Right
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Applying Text Decoration in CSS

    You can use the text-decoration property for adding extra decoration to the text, such as adding a line (underline, strikethrough, overline), color, style, and thickness to the line.

    It is a shorthand property for text-decoration-linetext-decoration-styletext-decoration-color, and text-decoration-thickness.

    Syntax

    The syntax for the text-decoration property is as follows:

    text-decoration: text-decoration-line text-decoration-color text-decoration-style text-decoration-thickness | initial | inherit;

    Example

    In this example, we have used the text-decoration property to apply overline, line-through, and underline styles with different colors, thicknesses, and line types.

    <!DOCTYPE html><html><body><h2>Text Decoration</h2><p style="text-decoration: overline solid red 5px;">
    
        Overline text decoration.
    &lt;/p&gt;&lt;p style="text-decoration: line-through solid green 1px;"&gt;
        Line-through text decoration.
    &lt;/p&gt;&lt;p style="text-decoration: underline dashed 2pt blue;"&gt;
        Underline text decoration.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Using CSS text-transform for Text Styling

    To change the appearance of text, the text-transform property is used. It transforms the text in various ways such as converting the text to uppercase, or lowercase, capitalizing the first letter of each word, or even capitalizing all letters.

    Example

    In this example, we have used the text-transform property to transform the text to uppercase, lowercase, and capitalize.

    <!DOCTYPE html><html><head><style>
    
        p{
            font-family: arial, sans-serif;
            font-size: 1em;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;Text Transform&lt;/h2&gt;&lt;p style="text-transform: capitalize;"&gt;
        capitalizes the first character of each word.
    &lt;/p&gt;&lt;p style="text-transform: uppercase;"&gt;
        Transforms all text to uppercase.
    &lt;/p&gt;&lt;p style="text-transform: lowercase;"&gt;
        Transforms all text to Lowercase.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Adding Text Emphasis in CSS

    To apply emphasis marks on a block of text, you can use the text-emphasis property. These marks are typically used to highlight specific content or to indicate pronunciation or stress in certain languages.

    It is a shorthand property for text-emphasis-style and text-emphasis-color.

    Example

    In this example, we have used the text-emphasis property to apply emphasis marks to the text.

    <!DOCTYPE html><html><head><style>
    
        p{
            font-family: arial, sans-serif;
            font-size: 1em;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;Text Emphasis&lt;/h2&gt;&lt;p style="text-emphasis: dot;"&gt; 
            The text is emphasized using dot.
        &lt;/p&gt;&lt;p style="text-emphasis: circle red;"&gt;
            The text is emphasized using red circle.
        &lt;/p&gt;&lt;p style="text-emphasis: triangle;"&gt; 
            The text is emphasized using triangle.
        &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Text Indentation Property

    To add space between the margin and the first line of text, you can use the text-indent property. A proper indentation improves the readability and clarity of text on a page.

    Example

    In this example, we have used the text-indent property to indent the first line of the text of the paragraphs.

    <html><body><h2>Text indentation</h2><p style="text-indent: 2cm;">Text indentation: 2 cm.</p><p style="text-indent: 2in;">Text indentation: 2 inches.</p><p style="text-indent: 20%;">Text indentation: 20%.</p></body></html>

    Letter Spacing in CSS

    To adjust the space between the letters of a text, you can use the letter-spacing property. The space can be increased or decreased between the letters.

    Example

    In this example, we have used the letter-spacing property to increase and decrease the space between the letters of the text.

    <!DOCTYPE html><html><body><h2>Letter spacing</h2><p style="letter-spacing: normal;">
    
        Letter spacing normal.
    &lt;/p&gt;&lt;p style="letter-spacing: 5px;"&gt;
        Letter spacing increased.
    &lt;/p&gt;&lt;p style="letter-spacing: -1px;"&gt;
        Letter spacing decreased.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Applying word-spacing in CSS

    The word-spacing property is used to adjust the space between the words of a text. The space can be increased or decreased between the words.

    Example

    In this example, we have used the word-spacing property to increase and decrease the space between the words of the text.

    <!DOCTYPE html><html><body><h2>Word spacing</h2><p style="word-spacing: normal;">
    
        Word spacing normal.
    &lt;/p&gt;&lt;p style="word-spacing: 100px;"&gt;
        Word spacing increased.
    &lt;/p&gt;&lt;p style="word-spacing: -2px;"&gt;
        Word spacing decreased.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Wrapping Text with white-space Property

    The white-space property controls how you can handle the white space inside an element. It allows you to manage the handling of spaces, tabs, and line breaks in the text.

    Example

    Here is an example of the white-space property using different values to control the white space inside the text.

    <!DOCTYPE html><html><head><style>
    
        p{
            border: 2px solid;
            padding: 5px;
            width: 50%;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;White-space property&lt;/h2&gt;&lt;p style="white-space: normal;"&gt;
        This is a paragraph with the white-space property set 
        to normal. The text will wrap when necessary, and 
        extra    spaces and line breaks are    ignored.
    &lt;/p&gt;&lt;p style="white-space: nowrap;"&gt;
        This is a paragraph with the white-space property set
        to nowrap. The text will not wrap to the next line, even 
        if it overflows the container.
    &lt;/p&gt;&lt;p style="white-space: pre;"&gt;
        This is a paragraph with white-space property set to pre.
        The text will respect all   spaces and line breaks. Means,
        the   text will be displayed as it is in     HTML code.
    &lt;/p&gt;&lt;p style="white-space: pre-wrap;"&gt;
        This is a paragraph with the white-space property set to
        pre-wrap. The text will respect all spaces and line breaks,
        but will wrap when necessary.
    &lt;/p&gt;&lt;p style="white-space: pre-line;"&gt;
        This is a paragraph with the white-space property set 
        to pre-line. The text will collapse spaces and wrap when 
        necessary, but will respect line breaks.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Line-Break Property

    To control how line breaks are handled in text, we use the CSS line-break property. This property is useful for handling line breaks in languages like Japanese, Chinese, or Korean. You can use values such as auto, loose, normal, strict, and anywhere with this property.

    Example

    In this example, we have used the line-break property with different values to control how the text breaks across lines based on language rules.

    <!DOCTYPE html><html><head><style>
    
        p{
            border: 2px solid;
            padding: 5px;
            width: 50%;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;Line-break property&lt;/h2&gt;&lt;p style="line-break: auto;"&gt;
        This paragraph uses the line-break property set to auto.
        Line breaking is determined based on the default rules.
    &lt;/p&gt;&lt;p style="line-break: loose;"&gt;
        This paragraph uses the line-break property set to loose.
        Line breaking is done more frequently, typically used in 
        CJK (Chinese, Japanese, Korean) text.
    &lt;/p&gt;&lt;p style="line-break: normal;"&gt;
        This paragraph uses the line-break property set to normal.
        Line breaking follows the standard rules for the language 
        being used.
    &lt;/p&gt;&lt;p style="line-break: strict;"&gt;
        This paragraph uses the line-break property set to strict.
        Line breaking is restricted, typically preventing breaks 
        between characters that are normally kept together.
    &lt;/p&gt;&lt;p style="line-break: anywhere;"&gt;
        This paragraph uses the line-break property set to anywhere.
        Line breaks can happen at any point, even if it means 
        breaking words in unconventional places.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Word-Break Property

    The word-break property controls the behavior of word breaking and word wrapping in text. It handles the words when they are too long to fit within their container. You can use values such as normal, break-all, keep-all, and break-word with this property.

    Example

    In this example, we have used the word-break property with different values to control how the word breaks to fit their container.

    <!DOCTYPE html><html><body><h2>Word-break property</h2><p style="word-break: normal;">
    
        This paragraph uses the word-break property set to &lt;strong&gt;normal&lt;/strong&gt;. 
        Words will break only at normal word boundaries (such as 
        spaces or hyphens).
    &lt;/p&gt;&lt;p style="word-break: break-all;"&gt;
        This paragraph uses the word-break property set to &lt;strong&gt;break-all&lt;/strong&gt;.
        Words will break at any character to prevent overflow, 
        even in the middle of a word.
    &lt;/p&gt;&lt;p style="word-break: keep-all;"&gt;
        This paragraph uses the word-break property set to &lt;strong&gt;keep-all&lt;/strong&gt;.
        Words will only break at normal word boundaries, but CJK text 
        characters will not break unless necessary.
    &lt;/p&gt;&lt;p style="word-break: break-word;"&gt;
        This paragraph uses the word-break property set to &lt;strong&gt;break-word&lt;/strong&gt;.
        Words will break at normal boundaries or wherever necessary 
        to prevent overflow.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS line-height Property

    To specify the height of a line of a text, you can use the CSS line-height property . It controls the spacing between lines.

    Example

    In this example, we have used the line-height property to increase the space between lines.

    <!DOCTYPE html><html><head><style>
    
        p {
            width: 300px;
            line-height: 2;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;line-height property&lt;/h2&gt;&lt;p&gt;This paragraph has a line height of 2, making the text more readable and spaced out.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Creating Text Shadows with CSS

    The text-shadow property is used to add a shadow effect to the text. It allows you to create a shadow behind the text by specifying the shadow's horizontal and vertical offsets, blur radius, and color.

    You can apply multiple shadows by separating each shadow with a comma. The order of the shadows matters, with the first shadow being closest to the text.

    Example

    In this example, we have used the text-shadow property to apply different shadow effects to the paragraphs, including single and multiple shadows with different offsets, colors, and blur radii.

    <!DOCTYPE html><html><head><style>
    
        .txt1 {
            text-shadow: 2px 2px 5px grey;
        }
        .txt2 {
            text-shadow: -2px -2px 3px red;
        }
        .txt3 {
            text-shadow: 3px 3px 0px blue, -3px -3px 0px yellow;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;Text-shadow property&lt;/h2&gt;&lt;p class="txt1"&gt;
        This text has a grey shadow with a blur radius of 5px.
    &lt;/p&gt;&lt;p class="txt2"&gt;
        This text has a red shadow with a blur radius of 3px 
        and offset to the top-left.
    &lt;/p&gt;&lt;p class="txt3"&gt;
        This text has two shadows: a blue shadow offset to the 
        bottom-right and a yellow shadow offset to the top-left.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS text-orientation Property

    To control the text orientation in vertical writing modes, we use the text-orientation property.

    Example

    In this example, we have used the text-orientation property to rotate the text vertically.

    <!DOCTYPE html><html><head><style>
    
        p {
            writing-mode: vertical-rl;
            text-orientation: upright;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;text-orientation property&lt;/h2&gt;&lt;p&gt;This text is displayed in a vertical layout using text-orientation.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

  • Fonts

    CSS fonts allows to customize font style of webpages using various font related properties. In this tutorial we will understand the font styling in CSS.

    What is CSS Font?

    In CSS, the font property is used to style and adjust type of text used in webpage.

    You can define fonts and customize their appearance by setting properties like font-familyfont-sizefont-weight and font-style. You can also use the shorthand property font to manipulate all the font style.

    Types of CSS Fonts

    • Monospace Fonts: The font in which every letter have equal width.
    • Serif Fonts: Have small stroke at the edge of each letter.
    • San-Serif Fonts: Clean fonts with out any strokes.
    • Fantasy Fonts: Decorative fancy fonts.
    • Cursive Fonts: The font that resembles human handwriting.

    Popular CSS Fonts

    Here is a table with some popular font and their generic font-family.

    Generic Font FamilyExamples of Font Names
    SerifTimes New Roman
    Georgia
    Garamond
    Sans-serifArial
    Verdana
    Helvetica
    MonospaceCourier New
    Lucida Console
    Monaco
    CursiveBrush Script MT
    Lucida Handwriting
    FantasyCopperplate
    Papyrus

    Setting Text Fonts

    The font-family property is used to specify font name for a text content.

    Example

    In this example, we have used the font-family property to set the font of the paragraph element.

    <html><head><style>
    
        p {
            font-family: Lucida Handwriting, Cursive;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;p &gt;
        This is a font that written in Lucida 
        Handwriting. THis is a font that looks 
        like human handwriting.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Setting Text Font Size

    To set the font size of the text, we use font-size property. You can use its values such as small, medium, and, large to get a variety of font sizes of the text.

    Example

    In this example, we have used the font-size property with its different values to set the size of the text.

    <!DOCTYPE html><html lang="en"><head><title>Font Size Example</title><style>
    
        .small {
            font-size: small;
        }
        .medium {
            font-size: medium;
        }
        .larger {
            font-size: larger;
        }
        .px {
            font-size: 18px;
        }
        .percent {
            font-size: 120%;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;CSS Font-Size Examples&lt;/h2&gt;&lt;p class="small"&gt;This text has a 'small' font size.&lt;/p&gt;&lt;p class="medium"&gt;This text has a 'medium' font size.&lt;/p&gt;&lt;p class="larger"&gt;This text has a 'larger' font size.&lt;/p&gt;&lt;p class="px"&gt;This text has a font size of 18px.&lt;/p&gt;&lt;p class="percent"&gt;This text has a font size of 25%.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Setting Font Weight

    You can use the font-weight property to set the boldness of the text.

    Example

    In this example, we have used the font-weight property to set the boldness of the text. The valid numeric value is from 100-900 for number class.

    <!DOCTYPE html><html lang="en"><head><title>CSS font-weight Property Example</title><style>
    
        .normal {
            font-weight: normal;
        }
        .bold {
            font-weight: bold;
        }
        .lighter {
            font-weight: lighter;
        }
        .number {
            font-weight: 600;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;CSS font-weight Property&lt;/h2&gt;&lt;p class="normal"&gt;This text has a 'normal' font-weight.&lt;/p&gt;&lt;p class="bold"&gt;This text has a 'bold' font-weight.&lt;/p&gt;&lt;p class="lighter"&gt;This text has a 'lighter' font-weight.&lt;/p&gt;&lt;p class="number"&gt;This text has a font-weight of 600.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Setting Font Style

    To set the style of the written text, we use the font-style property. The text can be set to normal, italic or oblique.

    Example

    In this example, we have used font-style property to set the style of the written text.

    <!DOCTYPE html><html lang="en"><head><title>CSS font-style Property Example</title><style>
    
        .normal {
            font-style: normal;
        }
        .italic {
            font-style: italic;
        }
        .oblique {
            font-style: oblique;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h2&gt;CSS font-style Property&lt;/h2&gt;&lt;p class="normal"&gt;It has 'normal' font-style.&lt;/p&gt;&lt;p class="italic"&gt;It has 'italic' font-style.&lt;/p&gt;&lt;p class="oblique"&gt;It has 'oblique' font-style.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Font Shorthand Property

    You can use the font shorthand property to modify size, weight, and style of texts.

    Example

    In this example, we have used the font shorthand property to set font style, weight, size and family.

    <html><head><style>
    
    .font-example {
        /* in-order: font style, weight, size, family */
        font: italic bold 20px Arial, sans-serif; 
    }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;p class="font-example"&gt;
        This is an example of text with an adjusted 
        font style, weight, and size using the font 
        shorthand property.
    &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS uses color values to specify a color. Typically, these are used to set a color either for the foreground of an element (i.e. its text) or else for the background of the element. They can also be used to affect the color of borders and other decorative effects.

    You can specify your color values in various formats. Following table lists all the possible formats −

    FormatSyntaxDescriptionExample
    Keyword<property>: <colorname>CSS has a set of predefined color names that you can use directly.red, blue, green, yellow, black, white, etc.
    Hexadecimal Code#RRGGBBStarts with a hash (#) followed by six hexadecimal digits.#FF0000 – red
    Short Hexadecimal Code#RGBShorter version of hexadecimal format where each of the RGB components is represented by a single digit, and the value is duplicated.#F00 – red
    RGBrgb(red,green,blue)Colors can be defined using the rgb() function, which takes three parameters representing the red, green, and blue values.rgb(0, 0, 255) – blue
    RGBArgba()Similar to RGB, with an additional parameter for the alpha (transparency) value. 0 (fully transparent) and 1 (fully opaque)rgba(0,0,255,0.5) – translucent blue
    HSLhsl()Colors can be defined using the rgb() function which stands for Hue (0 to 360 degree), Saturation (%), and Lightness (%).hsl(120, 100%, 50%) – pure green
    HSLAhsla()Similar to HSL, with an additional parameter for the alpha (transparency) value.hsl(120, 100%, 50%, 0.5) – translucent green
    currentcolor KeywordcurrentcolorIt refers to the value of the color property of the element.color: red; /* Red text color */ border: 10px solid currentcolor; /* Red border color */
    System coloras per OS or browserCSS allows usage of system colors defined by the user’s OS or browser.ButtonText, Window, WindowText

    These formats are explained in more detail in the following sections −

    CSS Colors – Keyword

    CSS supports the color names to be directly passed to the property background-color and color. 140 standard color names are supported by CSS.

    Few of the examples are listed in the table below:

    ColorColor Name
     Black
     Red
     Blue
     Green
     Aquamarine

    Here is an example:

    <html><head><style>
       #colorkeyword{
    
      background-color: aqua;
      padding: 10px;
    } </style></head><body><h3>Color Keyword - example</h3><p>As the keyword passed is aqua, the background will appear as aqua colored..</p><div id="colorkeyword">
      This div element has a colored background based on the color keyword passed, i.e aqua.
    </div></body></html>

    CSS Colors – Hexadecimal Codes

    A hexadecimal is a 6 digit representation of a color. The first two digits(RR) represent a red value, the next two are a green value(GG), and the last are the blue value(BB).

    A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.

    Each hexadecimal code will be preceded by a pound or hash sign ‘#’. Following are the examples of hexadecimal notation.

    Note: To specify the hexadecimal codes, you can use upper case or lower case letters.

    ColorColor Hexadecimal Code
     #000000
     #FF0000
     #00FF00
     #0000FF
     #FFFF00
     #00FFFF
     #FF00FF
     #C0C0C0
     #FFFFFF

    Here is an example:

    <html><head><style>
       #hexcode {
    
      background-color: #00ff00;
      padding: 10px;
    } </style></head><body><h3>Hexadecimal code - example</h3><p>As the hexadecimal code is #00ff00 the background will appear green.</p><div id="hexcode">
         This div element has a green background.
      &lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Colors - Short Hexadecimal Codes

    This is a shorter form of the six-digit notation. In this format, each digit is replicated to arrive at an equivalent six-digit value. For example: #6A7 becomes #66AA77.

    A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro, or even using Advanced Paint Brush.

    Each short hexadecimal code will be preceded by a pound or hash sign '#'. Following are the examples of short hexadecimal notation.

    Note: To specify the hexadecimal codes, you can use upper case or lower case letters.

    ColorShort Hexadecimal Code
     #000
     #F00
     #0F0
     #0FF
     #FF0
     #0FF
     #F0F
     #FFF

    Here is an example:

    <html><head><style>
       #shorthex {
    
      background-color: #00f;
      padding: 10px;
    } </style></head><body><h3>Short Hexadecimal code - example</h3><p>As the short hexadecimal code is #00f the background will appear blue.</p><div id="shorthex">
         This div element has a blue background.
      &lt;/div&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Colors - RGB Values

    • This color value is specified using the rgb( ) property.
    • It takes three values, one each for red, green, and blue.
    • The value can be an integer between 0 and 255 or a percentage.

    NOTE: All the browsers does not support rgb() property of color so it is recommended not to use it.

    Following is the example to show few colors using RGB values.

    ColorColor RGB
     rgb(0,0,0)
     rgb(255,0,0)
     rgb(0,255,0)
     rgb(0,0,255)
     rgb(255,255,0)
     rgb(0,255,255)
     rgb(255,0,255)
     rgb(192,192,192)
     rgb(255,255,255)

    Here is an example:

    <html><head><style>
       #rgbvalue {
    
      background-color: rgb(255,0,255);
      padding: 10px;
    } </style></head><body><h3>RGB - example</h3><p>As the rgb(255,0,255) is set the background will appear accordingly.</p><div id="rgbvalue">
      This div element has a colored background based on the rgb values.
    </div></body></html>

    CSS Colors - RGBA Values

    • This color value is specified using the rgba( ) property.
    • It takes four values, one each for red, green, and blue and the last value as the alpha (transparency) value.
    • The alpha value can be any value between 0 and 1.

    NOTE: All the browsers do not support rgba() property of color so it is not recommended.

    Following is the example to show few colors using RGBA values.

    ColorColor RGBA
     rgba(0,0,0,0)
     rgba(255,0,0,0.2)
     rgba(0,255,0,0.3)
     rgba(0,0,255,0.5)
     rgba(255,255,0,0.7)
     rgba(0,255,255,0.1)
     rgba(255,0,255,1)
     rgba(192,192,192,0.4)
     rgba(255,255,255,1)

    Here is an example:

    <html><head><style>
       #rgbavalue {
    
      background-color: rgba(255,0,255,0.2);
      padding: 10px;
    } </style></head><body><h3>RGBA - example</h3><p>As the rgba(255,0,255,0.2) is set the background will appear with transparency value of 0.2.</p><div id="rgbavalue">
      This div element has a colored background based on the rgba values.
    </div></body></html>

    CSS Colors - HSL Values

    • This color value is specified using the hsl() function.
    • HSL stands for hue, saturation and lightness.
    • Hue is represented in degrees (0-360), saturation and lightness are represented as percentages (0% - 100%).

    Following is the example to show few colors using HSL property.

    ColorColor HSL
     hsl(0,0%,50%)
     hsl(255,80%,70%)
     hsl(290,100%,60%)
     hsl(360,70%,20%)
     hsl(89,80%,67%)

    Here is an example:

    <html><head><style>
       #hslvalue {
    
      background-color: hsl(355,70%,50%);
      padding: 10px;
    } </style></head><body><h3>HSL - example</h3><p>As the hsl(355,70%,50%) is set the background will appear based on the hsl values passed.</p><div id="hslvalue">

  • Selectors

    CSS Selectors are used to select the HTML elements you want to style on a web page. They allow you to target specific elements or groups of elements to apply styles like colors, fonts, margins, and more.

    The element or elements that are selected by the selector are referred to as subject of the selector.

    CSS Universal Selector

    CSS universal selector is a special selector that selects all the elements in an HTML document. It is denoted by an asterisk mark (*).

         This paragraph is inside a div 
         and will be blue.
      &lt;/p&gt;&lt;section&gt;&lt;p&gt;
            This paragraph is inside a 
            section which is inside a 
            div and will also be blue.
         &lt;/p&gt;&lt;/section&gt;&lt;/div&gt;&lt;p&gt;
      This paragraph is outside the div 
      and will not be blue.
    </p></body></html>

    CSS Child Selector

    CSS child selector selects all the direct child of a particular element. This is denoted by '>' (Greater than) symbol.

    Syntax

    The syntax for the child selector is as follows:

    div > p{color: blue;}

    The above code set text color of paragraph tags that are directly inside div element to blue.

    Example

    The following example shows how to use child selector in css:

    <!DOCTYPE html><html lang="en"><head><style>
    
      div{
         border: 2px solid;
      }
      div &gt; p {
         color: blue;
      }
    </style></head><body><div><p>
            This paragraph is inside a div and 
            will be blue.
         &lt;/p&gt;&lt;section&gt;&lt;p&gt;
               This paragraph is inside a  
               section which is inside a div
               and will not be blue as this 
               is not direct child
            &lt;/p&gt;&lt;/section&gt;&lt;/div&gt;&lt;p&gt;
         This paragraph is outside the div
         and will not be blue.
      &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Adjacent Sibling Selectors

    CSS adjacent sibling selector selects an element that is immediately preceded by a specified element. A plus symbol ( "+" ) is used to denote adjacent sibling.

    Syntax

    The syntax of adjacent sibling selector is as follows:

    h1 + p{margin-top: 0;}

    The above code sets top margin of paragraph tag just after h1 tag to 0.

    Example

    The following example shows how to use adjacent sibling selector in css.

    <!DOCTYPE html><html lang="en"><head><style>
    
      div{
         border: 4px solid;
      }
      div + p {
         color: blue;
      }
    </style></head><body><p>
         This paragraph is above the div 
         and will not be blue
      &lt;/p&gt;&lt;div&gt;&lt;p&gt;
            This paragraph is inside a div 
            and will not be blue.
         &lt;/p&gt;&lt;/div&gt;&lt;p&gt;
         This paragraph 1 after the div 
         and will be blue.
      &lt;/p&gt;&lt;p&gt;This paragraph 2 after the 
         div and will not be blue.
      &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS General Sibling Selector

    general sibling selector targets all the element that is preceded by a specified element. The general sibling selector is denoted by tilde symbol ( "~" ).

    Syntax

    The syntax of general sibling selector is as follows:

    h1 ~ p{color: gray;}

    The above code sets text color of all the paragraph after h1 tag to gray.

    Example

    The following example shows how to use general sibling selector in css:

    <!DOCTYPE html><html lang="en"><head><style>
    
      div{
         border: 4px solid;
      }
      div ~ p {
         color: blue;
      }
    </style></head><body><p>
         This paragraph is above the div 
         and will not be blue
      &lt;/p&gt;&lt;div&gt;&lt;p&gt;
            This paragraph is inside a div 
            and will not be blue.
         &lt;/p&gt;&lt;/div&gt;&lt;p&gt;
         This paragraph 1 after the div 
         and will be blue.
      &lt;/p&gt;&lt;p&gt;This paragraph 2 after the 
         div and will be blue.
      &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    CSS Nested Selectors

    CSS nesting allows to nest one style rule inside another rule, with the selector of the child rule relative to the selector of the parent rule.

    Characteristics

    The nesting selector shows the relationship between the parent and child rules.

    • When the nested selectors are parsed by the browser, it automatically adds a whitespace between the selectors, thus creating a new CSS selector rule.
    • In situations where the nested rule needs to be attached to the parent rule (without any whitespace), like while using the pseudo-class or compound selectors, the & nesting selector must be prepended immediately to achieve the desired result.
    • In order to reverse the context of rules, the & nesting selector can be appended.
    • There can be multiple instances of & nesting selector.

    Syntax

    The syntax for the nesting selector is as follows:

    nav{& ul{list-style: none;& li{display: inline-block;& a{text-decoration: none;color: blue;&:hover{color: red;}}}}}

    Example

    The following example demonstrates the use of a nesting selector (&):

    <html><head><style>
    
      #sample {
         font-family: Verdana, Geneva, Tahoma, sans-serif;
         font-size: 1.5rem;
         &amp; a {
            color: crimson;
            &amp;:hover,
            &amp;:focus {
               color: green;
               background-color: yellow;
            }
         }
      }
    </style></head><body><h1>& nesting selector</h1><p id="sample">
      Hover &lt;a href="#"&gt;over the link&lt;/a&gt;.
    </p></body></html>

  • Units

    CSS Units define the measurement system used to specify the values. CSS offers a number of different units for expressing length and measurement. CSS unit is used to specify the property size for a page element or its content.

    There are a number of ways to specify and measure length in CSS. It is used to specify margins, padding, font size, width, height, border, etc.

    For example – font-size: 50px, here number 50 has a suffix px i.e., pixel, it is a CSS measurement unit.

    There should be no whitespace between the number and the unit. The unit can be left out when the value is 0.

    Length Units

    Length units can be categorized into two types:

    • Absolute units: Fixed unit lengths that does not depend on screen width.
    • Relative units: Responsive unit lengths that changes according to screen width.

    Absolute Length Units

    These units are categorized as fixed-length units, which means that lengths specified with absolute units maintain an exact, unchanged size on the screen.

    These units prove to be very effective when the browser has comprehensive information about the properties of the screen, the printer being used, or other appropriate user agents.Height: 2pxHeight: 2cmHeight: 2inHeight: 2pt

    The following table contains all the types of absolute units:

    UnitDescriptionEquivalent valueExample
    mmRefers to millimeter, it is used to specify the measurements in millimeters.1mm = 1/10th of 1cmfont-size: 10mm;
    cmRefers to centimeter, it is used to specify the measurements in centimeters.1cm = 37.8px = 25.2/64infont-size: 5cm;
    QRefers to Quarter-millimeters, it is used to specify the measurements in centimeters.1Q = 1/40th of 1cmfont-size: 5Q;
    inRefers to inches, it is used to specify the measurement in inches.1in = 2.54cm = 96pxfont-size: 1in;
    ptRefers to point, it is used to specify the measurements in points.1pt = 1/72 of 1infont-size: 20pt;
    pcRefers to picas, it is used to specify the measurement in picas.1pc = 1/6th of 1inwidth: 6pc;
    pxRefers to pixels, it is used to specify the measurement in pixels.1px = 1/96th of 1infont-size: 15px;

    Absolute units prove valuable for projects where responsiveness is not a priority. However, they are less beneficial for responsive websites because they do not adjust when screen dimensions change.

    Example

    Here is an example of absolute units (mm, cm, in, Q) used for font sizes:

    <html><head><style>
    
        .unit-mm {
            font-size: 5mm;
        }
        .unit-cm {
            font-size: 1cm;
        }
        .unit-inch {
            font-size: 0.5in;
        }
        .unit-quarter {
            font-size: 40Q;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h1 class="unit-mm"&gt; Font size 5mm &lt;/h1&gt;&lt;h1 class="unit-cm"&gt; Font size 1cm &lt;/h1&gt;&lt;h1 class="unit-inch"&gt; Font size 0.5inch &lt;/h1&gt;&lt;h1 class="unit-quarter"&gt; Font size 40Q &lt;/h1&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Relative Length Units

    Relative length units are measured in relation to other elements or viewport of the screen.

    Relative units are great for styling responsive websites because they can be adjusted proportionally based on window size or parent elements. These units define lengths relative to other length properties.Height: 3emHeight: 3exHeight: 3lhHeight: 3vh

    The following table contains all the types of relative units:

    UnitDescriptionExample
    emRelative to the font-size of the element.font-size: 4em;
    exRelative to the x-height of the current font.font-size: 4ex;
    chRelative to width of the "0".font-size: 4ch;
    remRelative to font-size of the root element.font-size: 2rem;
    lhIt is relative to the line height of the element.font-size: 4lh;
    rlhIt is relative to the line height of the root element.font-size: 4rlh;
    vhIt is relative to the height of the viewport. 1vh = 1% or 1/100 of the height of the viewport.font-size: 4vh;
    vwIt is relative to the width of the viewport. 1vw = 1% or 1/100 of the width of viewport.width: 4vw;
    vminIt is relative to the smaller dimension of the viewport. 1vmin = 1% or 1/100 of the viewport's smaller dimension.width: 4vmin;
    vmaxIt is relative to the larger dimension of the viewport. 1vmax = 1% or 1/100 of the viewport's larger dimension.width: 4vmax;
    vbIt is relative to the size of the initial containing block in the direction of the root element's block axis. 1vb = 1% of containing block's size (block axis).font-size: 4vb;
    viIt is relative to the size of the initial containing block in the direction of the root element's inline axis. 1vb = 1% of containing block's size (inline axis).font-size: 4vi;
    svw, svhIt is relative to the width and height of the smaller viewport. 1svw = 1% or 1/100 of the smaller viewport's width and 1svh = 1% or 1/100 of the smaller viewport's height.width: 40svw; height: 40svh;
    lvw, lvhIt is relative to the width and height of the larger viewport. 1lvw = 1% or 1/100 of the larger viewport's width and 1lvh = 1% or 1/100 of the larger viewport's height.width: 40lvw; height: 40lvh;
    dvw, dvhIt is relative to the width and height of the dynamic viewport. 1dvw = 1% or 1/100 of the dynamic viewport's width and 1dvh = 1% or 1/100 of the dynamic viewport's height.width: 40dvw; height: 40dvh;

    Example

    Here is an example of relative units (em, rem, vw, vh, %) used for font sizes:

    <html><head><style>
    
        .unit-em {
            font-size: 2em;
        }
        .unit-rem {
            font-size: 1.5rem;
        }
        .unit-vw {
            font-size: 5vw;
        }
        .unit-vh {
            font-size: 5vh;
        }
        .unit-percent {
            font-size: 150%;
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;h1 class="unit-em"&gt;Font size 2em &lt;/h1&gt;&lt;h1 class="unit-rem"&gt;Font size 1.5rem &lt;/h1&gt;&lt;h1 class="unit-vw"&gt;Font size 5vw &lt;/h1&gt;&lt;h1 class="unit-vh"&gt;Font size 5vh &lt;/h1&gt;&lt;h1 class="unit-percent"&gt;Font size 150% &lt;/h1&gt;&lt;/body&gt;&lt;/html&gt;</pre>

    Units px (Pixel) and em (indicates size relative to the size of the font) are two of the measurement units of length. In order to convert px to em, try our free CSS - PX to EM Converter.

  • Types of CSS

    CSS stands for “Cascading Style Sheet”. It is a style sheet language used to control the layout and other visual aspects of the web pages. CSS plays an important role in modern web development by providing the tools necessary to create visually appealing, accessible, and responsive websites.

    There are three types of CSS which are mentioned below.

    • Inline CSS
    • Internal CSS
    • External CSS

    1. Inline CSS

    Inline CSS is applied directly to an HTML element using the style attribute. It has the highest priority among the three methods.

    Example 1

    In this example we have changed the text color using color property and font of the written text using inline CSS properties.

    <p style="color: #04af2f; font-family: Verdana, sans-serif;">
    
    This line is an inline-styled paragraph.
    </p>

    Example 2

    In this example we have changed the background color, height, width and text color of the div element using inline CSS properties.

    <div style="background-color: #04af2f;color: white;height: 100px;width: 250px">
    
    This line is an inline-styled paragraph.
    </p>

    2. Internal CSS

    Internal CSS is defined within the <style> tag inside the <head> section of an HTML document.

    Example 1

    In this example we have changed the text color and font of the written text using internal CSS properties.

    <!DOCTYPE html>
    <html lang="en">
    
    <head>
    
    &lt;style&gt;
        p{color: #04af2f;font-family: Verdana, sans-serif;}
    &lt;/style&gt;
    </head> <body>
    &lt;p&gt;This line is styled using internal CSS.&lt;/p&gt;
    </body> </html>

    Example 2

    In this example we have changed the background color, height, width and text color of the div element using internal CSS properties.

    <!DOCTYPE html>
    <html lang="en">
    
    <head>
    
    &lt;style&gt;
        p{background-color: #04af2f;color: white;height: 100px;width: 250px;}
    &lt;/style&gt;
    </head> <body>
    &lt;p&gt;This line is styled using internal CSS.&lt;/p&gt;
    </body> </html>

    3. External CSS

    External CSS is written in a separate .css file and linked to the HTML document using the <link> tag. This is the recommended method for large projects as it improves maintainability.

    Example

    Here is an example of External CSS having separate files for HTML and CSS.

    HTML File

    <!-- HTML file --><head><link rel="stylesheet" href="styles.css"></head><body><p>This line is styled using external CSS.</p></body>

    CSS File

    /* styles.css */p{color: #04af2f;font-family: Verdana, sans-serif;}

    Note: The specificity order for above three types of CSS is as follows: Inline CSS > Internal CSS > External CSS.

  •  Inclusion

    You need to include the CSS file in your HTML document before using it. There are multiple ways to include CSS in an HTML file, such as writing inline CSS, internal CSS, or including a CSS file.

    Styles can be associated with your HTML document in different ways, such as:

    • Inline CSS − The CSS styling is placed inside an HTML element tag, which has an effect only on that element.
    • Internal CSS − The CSS styling is placed inside the <style> tag, under the <head> tag.
    • External CSS − The CSS styling is placed in an external file (.css extension) inside the <link> tag, under the <head> tag.

    Embedded / Inline CSS – <style> Attribute

    You can use style attribute of any HTML element to define style rules. These rules will be applied to that element only.

    Syntax

    Here is the generic syntax −

    <element style = "...style rules....">

    The value of style attribute is a combination of style declarations separated by semicolon (;).

    Example

    The following example demonstrates the use of inline css styling:

    <html><head></head><body><div style = "border: 5px inset gold; background-color: black; width: 300px; text-align: center;"><h1 style = "color:#36C;">Hello World !!!</h1><p style = "font-size: 1.5em; color: white;">This is a sample CSS code.</p></div></body></html>

    Internal CSS – <style> Element

    You can put your CSS rules into an HTML document using the <style> element. This tag is placed inside the <head>…</head> tag. Rules defined using this syntax will be applied to all the elements available in the document.

    Syntax

    Here is the generic syntax −

    <head><style type = "text/css">
    
      h1 {
         color: #36CFFF; 
      }
      p {
         font-size: 1.5em;
         color: white;
      }
      div {
         border: 5px inset gold;
         background-color: black;
         width: 300px;
         text-align: center;
      }
    </style></head>

    Example

    The same style is applied in the following example:

    <html><head><style type = "text/css">
    
      h1 {
         color: #36CFFF; 
      }
      p {
         font-size: 1.5em;
         color: white;
      }
      div {
         border: 5px inset gold;
         background-color: black;
         width: 300px;
         text-align: center;
      }
    </style></head><body><div><h1>Hello World !!!</h1><p>This is a sample CSS code.</p></div></body></html>

    Attributes associated with <style> elements are −

    AttributePossible ValuesDescription
    typetext/cssSpecifies the style sheet language as a content-type (MIME type). This is a required attribute.
    mediascreenttytvprojectionhandheldprintbrailleauralallSpecifies the device the document will be displayed on. Default value is all. This is an optional attribute.

    External CSS – <link> Element

    The <link> element can be used to include an external stylesheet file in your HTML document.

    An external style sheet is a separate text file with .css extension. You can define all the style rules in this text file and include this file in any HTML document using the <link> element.

    Syntax

    Here is the generic syntax of including external CSS file −

    <head><link type = "text/css" href = "..." media = "..." /></head>

    Attributes associated with <style> elements are −

    AttributePossible ValuesDescription
    typetext cssSpecifies the style sheet language as a content-type (MIME type). This attribute is required.
    hrefURLSpecifies the style sheet file having style rules. This attribute is required.
    mediascreenttytvprojectionhandheldprintbrailleauralallSpecifies the device the document will be displayed on. Default value is all. This is an optional attribute.

    Create a style sheet file with a name ext_style.css having the following rules −

       h1 {
    
      color: #36CFFF; 
    } p {
      font-size: 1.5em;
      color: white;
    } div {
      border: 5px inset gold;
      background-color: black;
      width: 300px;
      text-align: center;
    }

    Example

    Now you can include this file ext_style.css in any HTML document as follows −

    <head><link type = "text/css" href = "ext_style.css"/></head>

    Following example demonstrates how to include an external css file in an HTML file:

    <html><head><link type = "text/css" href = "ext_style.css"/></head><body><div><h1>Hello World !!!</h1><p>This is a sample CSS code.</p></div></body></html>

    Imported CSS – @import Rule

    The @import is used to import an external stylesheet in a manner similar to the <link> element. The only key point to remember is, the @import rule must be declared on top of the document. Here is the generic syntax of @import rule.

    Syntax

    Refer the following two css files − style.css and demostyle.css

    style.css

    body {
       background-color: peachpuff;
    }
    

    demostyle.css

    @import url("style.css");
    
    h1 {
    
      color: #36CFFF; 
    } p {
      font-size: 1.5em;
      color: white
    } div {
      border: 5px inset gold;
      background-color: black;
      width: 300px;
      text-align: center
    }

    You just need to include the stylesheet, that has @import rule defined, in the <link> tag in the HTML document as follows −

    <head><link type = "text/css" href = "demostyle.css"></head>

    Example

    Following example demonstrates the use of @import rule, where one stylesheet can be imported into another stylesheet:

    <html><head><link type = "text/css" href = "demostyle.css"></head><body><div><h1>Hello World !!!</h1><p>This is a sample CSS code.</p></div></body></html>

    CSS Rules Overriding

    We have discussed different ways to include style sheet rules in an HTML document. Here is the rule to override any Style Sheet Rule.

    • Any inline style sheet takes highest priority. So, it will override any rule defined in <style>…</style> tags or rules defined in any external style sheet file.
    • Any rule defined in <style>…</style> tags will override rules defined in any external style sheet file.
    • Any rule defined in external style sheet file takes lowest priority, and rules defined in this file will be applied only when above two rules are not applicable.

    CSS Comments Inclusion

    Many times, you may need to put additional comments in your style sheet blocks. So, it is very easy to comment any part in style sheet. You can simple put your comments inside /*…..this is a comment in style sheet…..*/.

    You can use /* ….*/ to comment multi-line blocks.

    Example

    <html><head><style>
    
      h1 {
         color: #36CFFF; 
      }
      p {
         font-size: 1.5em;
         color: red;
         /* This is a single-line comment */
         text-align: center;
      }
      
      div {
         border: 5px inset gold;
         /* This is a multi-line comment
         background-color: black;
         width: 300px;
         text-align: center;
         */
      }
    </style></head><body><div><h1>Hello World !!!</h1><p>This is a sample CSS code.</p></div></body></html>

            color: white; 
            padding: 5px;
        }
        /* Style all elements with class 'special' */
        .special {
            color: lightblue; /* Change text color */
        }
    &lt;/style&gt;&lt;/head&gt;&lt;body&gt;&lt;p&gt;
        This a normal paragraph...
    &lt;/p&gt;&lt;br&gt;&lt;p class="special"&gt;
        This is a paragraph with class special...
    &lt;/p&gt;&lt;br&gt;&lt;div class="special"&gt;
