Answer 1

for general use on web pages in all browsers, include msRequestFullscreen

addEventListener("click", function () {
    var
          el = document.documentElement
        , rfs =
               el.requestFullScreen
            || el.webkitRequestFullScreen
            || el.mozRequestFullScreen
            || el.msRequestFullscreen
    ;
    if (rfs) { rfs.call(el); } else { console.log('fullscreen api not supported');}
});
