CSS - :fullscreen
The :fullscreen CSS pseudo-class applies to any element that's currently being displayed in full-screen mode. It selects not only to the top level element, but to the whole stack of elements that appears.
Example
HTML
<div id="fullscreen"> <h1>:fullscreen Demo</h1> <p> This will become a big red text when on fullscreen.</p> <button id="fullscreen-button">Enter Fullscreen</button> </div>
Javascript
var fullscreenButton = document.getElementById("fullscreen-button"); var fullscreenDiv = document.getElementById("fullscreen"); var fullscreenFunc = fullscreenDiv.requestFullscreen; if (!fullscreenFunc) { ['mozRequestFullScreen', 'msRequestFullscreen', 'webkitRequestFullScreen'].forEach(function (req) { fullscreenFunc = fullscreenFunc || fullscreenDiv[req]; }); } function enterFullscreen() { fullscreenFunc.call(fullscreenDiv); } fullscreenButton.addEventListener('click', enterFullscreen);

Description

:fullscreen, that is without a dash, but both the Webkit and Gecko experimental implementations use a prefixed variant with two words linked by a dash: :-webkit-full-screen and :-moz-full-screen, respectively. Microsoft Edge and Internet Explorer use the standard syntax: :fullscreen and :-ms-fullscreen, respectively.Browser Compatibility

[1] Both the Webkit and Gecko prefixed versions have a dash between full and screen, but the W3C proposal uses one single word: :fullscreen, :-webkit-full-screen, :-moz-full-screen.
[2] Gecko 47.0 (Firefox 47.0 / Thunderbird 47.0 / SeaMonkey 2.44) implements the unprefixed pseudo-class behind the preference full-screen-api.unprefix.enabled, defaulting to false.
[3] Internet Explorer uses the prefix -ms but does not have a dash between full and screen: :-ms-fullscreen.
