css伪类:fullscreen应用于当前处于全屏显示模式的元素。 它不仅仅选择顶级元素，还包括所有已显示的栈内元素。
:-webkit-full-screen 和:-moz-full-screen。微软的Edge和Internet Explorer各自使用标准语法：:fullscreen和:-ms-fullscreen。<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>
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);

[1] Webkit和Gecko前缀版本在full和screen之间带有破折号, 但W3C标准使用一个单词：:fullscreen, :-webkit-full-screen, :-moz-full-screen.
[2] Gecko 47.0 {{geckoRelease("47.0")}} 通过参数full-screen-api.unprefix.enabled使用不带前缀的伪类, 默认为false.
[3] Internet Explorer使用前缀-ms，但在full和screen之间没有破折号:-ms-fullscreen.
