How TO - Fullscreen


Learn how to make a fullscreen window with JavaScript.


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;
}
