How to make the window full screen with Javascript (stretching all over the screen)

Question

How can I make a visitor\'s browser go fullscreen using JavaScript, in a way that works with IE, Firefox and Opera?

Answer 1

Now that the full screen APIs are more widespread and appear to be maturing, why not try Screenfull.js? I used it for the first time yesterday and today our app goes truly full screen in (almost) all browsers!

Be sure to couple it with the :fullscreen pseudo-class in CSS. See https://www.sitepoint.com/use-html5-full-screen-api/ for more.
