Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The Document.fullscreen read-only property reports whether or not the document is currently displaying content in fullscreen mode.

Although this property is read-only, it will not throw if it is modified (even in strict mode); the setter is a no-operation and it will be ignored.

This property is deprecated; test if Document.fullscreenElement is not null instead.

Syntax

var isFullScreen = document.fullscreen;

Return value

  • A Boolean that is true if the document is being displayed in fullscreen mode; otherwise it's false.

Example

function isDocumentInFullScreenMode() {
  // Better: use fullscreenElement method!
  return document.fullscreen;  
}
