The Document method exitFullscreen() requests that the element on this document which is currently being presented in full-screen mode be taken out of full-screen mode, restoring the previous state of the screen.
The Document method exitFullscreen() requests that the element on this document which is currently being presented in full-screen mode be taken out of full-screen mode, restoring the previous state of the screen. This usually reverses the effects of a previous call to Element.requestFullscreen().
The exception is if another element was already in full-screen mode when the current element was placed into full-screen mode using requestFullscreen(). In that case, the previous full-screen element is restored to full-screen status instead. In essence, a stack of full-screen elements is maintained.
The exitPointerLock asynchronously releases a pointer lock previously requested through Element.requestPointerLock.
The exitPointerLock asynchronously releases a pointer lock previously requested through Element.requestPointerLock.
To track the success or failure of the request, it is necessary to listen for the pointerlockchange and pointerlockerror events.

The read-only fullscreenEnabled property on the Document interface indicates whether or not full-screen mode is available.
The read-only fullscreenEnabled property on the Document interface indicates whether or not full-screen mode is available. Full-screen mode is available only for a page that has no windowed plug-ins in any of its documents, and if all <iframe> elements which contain the document have their allowfullscreen attribute set.

Returns a string containing the date and time on which the current document was last modified.
Returns a DOMString representing the local part of the qualified name of an element.
Returns a DOMString representing the local part of the qualified name of an element. In Firefox 3.5 and earlier, the property upper-cases the local name for HTML elements (but not XHTML elements). In later versions, this does not happen, so the property is in lower case for both HTML and XHTML. Though the specification requires localName to be defined on the Node interface, Gecko-based browsers implement it on the Element interface.
Takes a prefix and returns the namespaceURI associated with it on the given node if found (and null if not).

The read-only Node.nodeType property returns an unsigned short integer representing the type of the node.
Is a DOMString representing the value of an object.

The visibilitychange event is fired when the content of a tab has become visible or has been hidden.
Each web page loaded in the browser has its own document object. The Document interface serves as an entry point to the web page's content (the DOM tree, including elements such as <body> and <table>) and provides functionality global to the document (such as obtaining the page's URL and creating new elements in the document).
