 With the Popover API, it is easier to build transient user interface elements that are displayed on top of all other web app UI. This includes user interactive elements like action menus, form element suggestion, content pickers, and teaching UI. The new Popover attribute enables any element to be displayed in the top layer automatically. This means no more worrying about positioning, stacking elements, focus, or keyboard interactions for developers. This is similar to the dialog element, but has several important differences, including like dismissed behavior, Popover interaction management, event support, and the lack of a modal mode.
