Fullscreen Window
How to use JavaScript to view an element in fullscreen mode.
Click on the button to open the video in fullscreen mode:
Fullscreen Video
To open an element in fullscreen, we use the element.requestFullscreen()
method:
Example
<script>
/* 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 method yet */
function openFullscreen() {
if (elem.requestFullscreen) {
elem.requestFullscreen();
} else if (elem.mozRequestFullScreen) { /*
Firefox */
elem.mozRequestFullScreen();
} else
if (elem.webkitRequestFullscreen) { /* Chrome, Safari and Opera */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen)
{ /* IE/Edge */
elem.msRequestFullscreen();
}
}
</script>

Fullscreen Document
To open the whole page in fullscreen, use the document.documentElement instead of document.getElementById("element").
In this example, we also use a close function to close the fullscreen:
Example
<script>
/* 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.mozRequestFullScreen) { /* Firefox */
elem.mozRequestFullScreen();
} else if (elem.webkitRequestFullscreen)
{ /* Chrome, Safari and Opera */
elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen)
{ /* IE/Edge */
elem.msRequestFullscreen();
}
}
/*
Close fullscreen */
function closeFullscreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.mozCancelFullScreen) { /* Firefox */
document.mozCancelFullScreen();
} else if (document.webkitExitFullscreen)
{ /* Chrome, Safari and Opera */
document.webkitExitFullscreen();
} else if (document.msExitFullscreen) { /* IE/Edge */
document.msExitFullscreen();
}
}
</script>
You can also use CSS to style the page when it is in fullscreen mode:
Example
/* Chrome, Safari and Opera syntax */
:-webkit-full-screen {
background-color: yellow;
}
/* Firefox syntax */
:-moz-full-screen {
background-color: yellow;
}
/* IE/Edge syntax */
:-ms-fullscreen {
background-color: yellow;
}
/* Standard syntax */
:fullscreen {
background-color: yellow;
}
