Practical Examples

Let’s explore some practical examples to see how the ::after pseudo-element can be used effectively.

Example 1: Adding a Decorative Element

You can use the ::after pseudo-element to add a decorative element after a heading.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Decorative Element</title>
	
    <style>
	
        h1::after {
            content: " ✨";
            color: gold;
            margin-left: 10px;
        }
    </style>
	
</head>
<body>

    <h1>Welcome to My Website</h1>
	
</body>
</html>

In this example, the h1::after selector adds a sparkling star after the heading text, enhancing its visual appeal.

Example 2: Adding an Icon After Links

You can use the ::after pseudo-element to add an icon after each link.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Icon After Links</title>
	
    <style>
	
        a::after {
            content: " 🔗";
            margin-left: 5px;
        }
		
    </style>
</head>
<body>

    <a href="https://example.com">Visit Example</a>
    <a href="https://another.com">Visit Another</a>
	
</body>
</html>

Here, the a::after selector adds a link icon after each anchor text, making the links more visually distinct.

Example 3: Creating a Custom List Style

You can use the ::after pseudo-element to create custom markers after list items.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Custom List Style</title>
	
    <style>
	
		    ul {
			      list-style: none;
		    }
	
        ul li::after {
            content: " •";
            color: red;
            font-weight: bold;
            margin-left: 10px;
        }
		
    </style>
</head>
<body>

    <ul>
        <li>First item</li>
        <li>Second item</li>
        <li>Third item</li>
    </ul>
	
</body>
</html>

In this example, the ul li::after selector adds a red, bold bullet after each list item, creating a custom list style.

Example 4: Adding Quotes After Blockquotes

You can use the ::after pseudo-element to add quotation marks after blockquote elements.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Quotes After Blockquotes</title>
    <style>
	
        blockquote::after {
            content: "”";
            font-size: 2em;
            color: gray;
            vertical-align: bottom;
            margin-left: 2px;
        }
		
    </style>
</head>
<body>

    <blockquote>
        This is a quote inside a blockquote.
    </blockquote>
	
</body>
</html>

Here, the blockquote::after selector adds a large gray quotation mark after the blockquote text, emphasizing the quoted text.
