popover

{{HTMLSidebar("Global_attributes")}} 

The popover global attribute is used to designate an element as a popover element.

Popover elements are hidden via display: none until opened via an invoking/control element (i.e. a <button> or <input type="button"> with a popovertarget attribute) or a {{domxref("HTMLElement.showPopover()")}}  call.

When open, popover elements will appear above all other elements in the {{glossary("top layer")}} , and won’t be influenced by parent elements’ {{cssxref('position')}}  or {{cssxref('overflow')}}  styling.

A popover attribute can have values "auto" (default) or "manual". Popovers that have the auto 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, manual popovers must always be explicitly hidden, but allow for use cases such as nested popovers in menus.

For detailed information on usage, see the {{domxref("Popover API", "Popover API", "", "nocode")}}  landing page.

Examples

The following renders a button that will open a popover element when activated.

<button popovertarget="my-popover">Open Popover</button>

<div popover id="my-popover">Greetings, one and all!</div>
