HTML Picture Element

The <picture> element provides a way to serve different images depending on screen size, device resolution, or other conditions. By using <source> elements with media queries or formats, you can offer responsive images, ensuring the best possible visual experience across various devices.

Key Topics

Using the Picture Element

Example: Different images loaded based on media conditions, such as screen width.

<picture>
    <source srcset="images/TryMeYourSelf-logo-3.png" media="(min-width:800px)">
    <img src="images/TryMeYourSelf-logo.png" alt="Responsive Logo">
</picture>

A Responsive Image Page

This example shows the <picture> element in action for a responsive page. Since this is a full HTML code demonstration, it is enclosed in a copy code box.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Responsive Image Example</title>
    <style>
        body {
            font-family: Arial, sans-serif;
        }
        .responsive-section {
            width: 100%;
            max-width: 600px;
            margin: 0 auto;
            text-align: center;
        }
    </style>
</head>
<body>
    <div class="responsive-section">
        <h1>Responsive Logo</h1>
        <picture>
            <source srcset="images/TryMeYourSelf-logo-2.png" media="(min-width:800px)">
            <source srcset="images/TryMeYourSelf-logo-1.png" media="(min-width:400px)">
            <img src="images/TryMeYourSelf-logo.png" alt="Responsive Logo" style="max-width:100%; height:auto;">
        </picture>
        <p>Resize the browser window to see the logo change based on the viewport width.</p>
    </div>
</body>
</html>

Explanation: The <picture> element uses multiple <source> elements with different media conditions. As the screen size changes, the browser selects the most appropriate image. This approach is vital for responsive design, optimizing both performance and user experience.

Picture Element in a Table

This demonstration places a <picture> element inside a table to display context-sensitive images. Another full code sample is provided below.

<h2>Responsive Image in a Table</h2>
<table border="1" style="border-collapse:collapse; width:60%; text-align:center;">
    <tr>
        <th>Responsive Logo</th>
    </tr>
    <tr>
        <td>
            <picture>
                <source srcset="images/TryMeYourSelf-logo-head.png" media="(min-width:600px)">
                <img src="images/TryMeYourSelf-logo.png" alt="Responsive Logo" style="max-width:100%; height:auto;">
            </picture>
            <p>The image changes based on screen size.</p>
        </td>
    </tr>
</table>

Explanation: Incorporating the <picture> element within a table cell allows responsive images in structured content layouts, adapting to various devices and viewport sizes to maintain optimal presentation.
