The Element.requestFullscreen() method issues an asynchronous request to make the element be displayed full-screen.

It's not guaranteed that the element will be put into full screen mode. If permission to enter full screen mode is granted, the document will receive a fullscreenchange event to let it know that it's now in full screen mode. If permission is denied, the document receives a fullscreenerror event instead.

Only elements which are in the HTML namespace (that is, elements which are standard HTML), plus the <svg> and <math> elements, which are located in the top-level document or in an <iframe> with the allowfullscreen attribute can be displayed full-screen. This means that elements inside a <frame> or an <object> can't.

Syntax

Element.requestFullscreen();

Example

Before calling requestFullScreen(), set up event handlers for the fullscreenchange and fullscreenerror events, so you know when you've successfully switched into full-screen mode (or when permission to do so has been denied).

[1] Also implemented as webkitRequestFullScreen.

[2] Implemented as mozRequestFullScreen (notice the capital S for Screen). Before Firefox 44, Gecko incorrectly allowed elements inside a <frame> or an <object> to request, and to be granted, fullscreen. In Firefox 44 and onwards this has been fixed: only elements in the top-level document or in an <iframe> with the allowfullscreen attribute can be displayed fullscreen.
