Fullscreen API requestFullscreen()
Example
Show a <video> element in fullscreen mode:
/* Get the element you want displayed in fullscreen mode (a video in this example): */
var elem = document.getElementById("myvideo");
/* When the openFullscreen() function is executed, open the video in fullscreen.
Note that we must include prefixes for different browsers, as they don't support the requestFullscreen property yet */
function openFullscreen() {
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) { /* Safari */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen) { /* IE11 */
elem.msRequestFullscreen();
}
}

elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) { /* Safari */
elem.webkitRequestFullscreen();

More Examples
To open the HTML page in fullscreen, use thedocument.documentElement instead ofdocument.getElementById("element"). In this example, we also use a close function to close the fullscreen:
Example
/* Get the documentElement (<html>) to display the page in fullscreen */
var elem = document.documentElement;
/* View in fullscreen */
function openFullscreen() {
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) { /* Safari */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen) { /* IE11 */
elem.msRequestFullscreen();
}
}
/* Close fullscreen */
function closeFullscreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.webkitExitFullscreen) { /* Safari */
document.webkitExitFullscreen();
} else if (document.msExitFullscreen) { /* IE11 */
document.msExitFullscreen();
}
}
Try it Yourself »var elem = document.documentElement;
/* View in fullscreen */
function openFullscreen() {
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) { /* Safari */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen) { /* IE11 */
elem.msRequestFullscreen();
}
}
/* Close fullscreen */
function closeFullscreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.webkitExitFullscreen) { /* Safari */
document.webkitExitFullscreen();
} else if (document.msExitFullscreen) { /* IE11 */
document.msExitFullscreen();
}
}
You can also use CSS to style the page when it is in fullscreen mode:
Example
/* Safari */
:-webkit-full-screen {
background-color: yellow;
}
/* IE11 syntax */
:-ms-fullscreen {
background-color: yellow;
}
/* Standard syntax */
:fullscreen {
background-color: yellow;
}
Try it Yourself »:-webkit-full-screen {
background-color: yellow;
}
/* IE11 syntax */
:-ms-fullscreen {
background-color: yellow;
}
/* Standard syntax */
:fullscreen {
background-color: yellow;
}
