fullscreenElement property

Element? get fullscreenElement

The Document.fullscreenElement read-only property returns the Element that is currently being presented in fullscreen mode in this document, or null if fullscreen mode is not currently in use.

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.

Implementation

external Element? get fullscreenElement;
