+<header><h1>&lt;picture&gt;: The Picture element</h1></header><div class="section-content">
+<p>The <code>&lt;picture&gt;</code> <a href="../index">HTML</a> element contains zero or more <a href="source"><code>&lt;source&gt;</code></a> elements and one <a href="img"><code>&lt;img&gt;</code></a> element to offer alternative versions of an image for different display/device scenarios.</p> <p>The browser will consider each child <code>&lt;source&gt;</code> element and choose the best match among them. If no matches are found—or the browser doesn't support the <code>&lt;picture&gt;</code> element—the URL of the <code>&lt;img&gt;</code> element's <a href="img#src"><code>src</code></a> attribute is selected. The selected image is then presented in the space occupied by the <code>&lt;img&gt;</code> element.</p>

+<iframe class="interactive is-tabbed-standard-height" height="200" src="https://interactive-examples.mdn.mozilla.net/pages/tabbed/picture.html" title="MDN Web Docs Interactive Example" loading="lazy"></iframe> <p>To decide which URL to load, the <a href="https://developer.mozilla.org/en-US/docs/Glossary/User_agent">user agent</a> examines each <code>&lt;source&gt;</code>'s <a href="source#srcset"><code>srcset</code></a>, <a href="source#media"><code>media</code></a>, and <a href="source#type"><code>type</code></a> attributes to select a compatible image that best matches the current layout and capabilities of the display device.</p> <p>The <code>&lt;img&gt;</code> element serves two purposes:</p> <ol> <li>It describes the size and other attributes of the image and its presentation.</li> <li>It provides a fallback in case none of the offered <code>&lt;source&gt;</code> elements are able to provide a usable image.</li> </ol> <p>Common use cases for <code>&lt;picture&gt;</code>:</p> <ul> <li>
+<strong>Art direction.</strong> Cropping or modifying images for different <code>media</code> conditions (for example, loading a simpler version of an image which has too many details, on smaller displays).</li> <li>
+<strong>Offering alternative image formats</strong>, for cases where certain formats are not supported. <div class="notecard note" id="sect1"> <p><strong>Note:</strong> For example, newer formats like <a href="https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Image_types#avif_image">AVIF</a> or <a href="https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Image_types#webp_image">WEBP</a> have many advantages, but might not be supported by the browser. A list of supported image formats can be found in: <a href="https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Image_types">Image file type and format guide</a>.</p> </div> </li> <li>
+<strong>Saving bandwidth and speeding page load times</strong> by loading the most appropriate image for the viewer's display.</li> </ul> <p>If providing higher-density versions of an image for high-DPI (Retina) display, use <a href="img#srcset"><code>srcset</code></a> on the <code>&lt;img&gt;</code> element instead. This lets browsers opt for lower-density versions in data-saving modes, and you don't have to write explicit <code>media</code> conditions.</p> <figure class="table-container"><div class="_table"><table class="properties"> <tbody> <tr> <th scope="row"><a href="../content_categories">Content categories</a></th> <td>
