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 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
elt.requestFullscreen();

[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.
