Window: fullScreen property

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

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!
}
