<header><h1>popover</h1></header><div class="section-content">
<p>The <code>popover</code> <a href="../global_attributes">global attribute</a> is used to designate an element as a popover element.</p> <p>Popover elements are hidden via <code>display: none</code> until opened via an invoking/control element (i.e. a <code><button></code> or <code><input type="button"></code> with a <a href="../element/button#popovertarget"><code>popovertarget</code></a> attribute) or a <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/showPopover"><code>HTMLElement.showPopover()</code></a> call.</p> <p>When open, popover elements will appear above all other elements in the <a href="https://developer.mozilla.org/en-US/docs/Glossary/Top_layer">top layer</a>, and won't be influenced by parent elements' <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/position"><code>position</code></a> or <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/overflow"><code>overflow</code></a> styling.</p> <p> A popover attribute can have values <a href="https://developer.mozilla.org/en-US/docs/Web/API/Popover_API/Using#auto_state_and_light_dismiss"><code>"auto"</code></a> (default) or <a href="https://developer.mozilla.org/en-US/docs/Web/API/Popover_API/Using#using_manual_popover_state"><code>"manual"</code></a>. Popovers that have the <code>auto</code> state can be "light dismissed" by selecting outside the popover area, and generally only allow one popover to be displayed on-screen at a time. By contrast, <code>manual</code> popovers must always be explicitly hidden, but allow for use cases such as nested popovers in menus. </p> <p>For detailed information on usage, see the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Popover_API">Popover API</a> landing page.</p>
