Pointer capture allows events for a particular pointer event (PointerEvent) to be re-targeted to a particular element instead of the normal target (or hit test) at a pointer's location. This can be used to ensure that an element continues to receive pointer events even if the pointer device's contact moves off the element (for example by scrolling).
A reference to the object that dispatched the event. It is different from event.currentTarget when the event handler is called during the bubbling or capturing phase of the event.
The Event.type read-only property returns a string containing the type of event. It is set when the event is constructed and is the name commonly used to refer to the specific event.
The Fullscreen API provides an easy way for web content to be presented using the user's entire screen. The API lets you easily direct the browser to make an element and its children, if any, occupy the fullscreen, eliminating all browser user interface and other applications from the screen for the duration.
