<header><h1><header></h1></header><div class="section-content"><p>The <code><header></code> <a href="../index">HTML</a> element represents introductory content, typically a group of introductory or navigational aids. It may contain some heading elements but also a logo, a search form, an author name, and other elements.</p></div>

<h2 id="usage_notes">Usage notes</h2>
<div class="section-content">
<p>The <code><header></code> element has an identical meaning to the site-wide <a href="https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/banner_role"><code>banner</code></a> landmark role, unless nested within sectioning content. Then, the <code><header></code> element is not a landmark.</p> <p>The <code><header></code> element can define a global site header, described as a <code>banner</code> in the accessibility tree. It usually includes a logo, company name, search feature, and possibly the global navigation or a slogan. It is generally located at the top of the page.</p> <p>Otherwise, it is a <code>section</code> in the accessibility tree, and usually contains the surrounding section's heading (an <code>h1</code> – <code>h6</code> element) and optional subheading, but this is <strong>not</strong> required.</p>
</div>
<h3 id="historical_usage">Historical Usage</h3>
<div class="section-content"><p>The <code><header></code> element originally existed at the very beginning of HTML for headings. It is seen in <a href="http://info.cern.ch/" target="_blank">the very first website</a>. At some point, headings became <a href="heading_elements"><code><h1></code> through <code><h6></code></a>, allowing <code><header></code> to be free to fill a different role.</p></div>
