Detecting if a browser is in full screen mode

Question

Is there any way of reliably detecting if a browser is running in full screen mode? I\'m pretty sure there isn\'t any browser API I can query, but has anyone worked it out b

Answer 1

To detect whether browser is in fullscreen mode:

document.webkitIsFullScreen || document.mozFullScreen || document.msFullscreenElement

according to caniuse you should be fine for majority of browsers.
