HTML popover Attribute - HTML Global Attributes

Definition and Usage

The popover attribute defines an element as a popover element, meaning that when it is invoked, it will be placed on top of the content, not interfere with the position of other HTML elements.

A popover element will be invisible until it is invoked by another element. The other element must have a popovertarget attribute where the value refers to the popover element's id.

The popover element will be placed on top of all other content, and by clicking the popovertarget element, the popover element will toggle between showing and hiding:

The popover element can be a single HTML element as in the example above, or an entire section of HTML elements like in the example below.
