Window: fullScreen property

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The fullScreen property of the Window interface indicates whether the window is displayed in full screen mode or not.

Value

A boolean value with true meaning that the window is in full-screen mode and false meaning it isn't.

Notes

  • Switching between regular window and full screen will fire the "resize" event on the corresponding window.

Examples

js
if (window.fullScreen) {
  // it's fullscreen!
} else {
  // not fullscreen!
}
