When an HTML document has been switched to designMode, the document object exposes the execCommand method which allows one to run commands to manipulate the contents of the editable region. Most commands affect the document's selection (bold, italics, etc), while others insert new elements (adding a link) or affect an entire line (indenting). When using contentEditable, calling execCommand will affect the currently active editable element.

.attributes is a collection of all attribute nodes registered to the specified node. It is a NamedNodeMap,not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attribute is a key value pair of strings that represents any information regarding that node; it cannot hold Object. Attribute can hold additional data/information that is required while processing custom JavaScript. There are many predefined attributes for different nodes used for binding events, validations, and specifying layout informations that are handled by browser (may vary from browser to browser).

Returns an XPathResult based on an XPath expression and other given parameters.
- Value parameters:
- contextNode
specifies the context node for the query (see the [http://www.w3.org/TR/xpath XPath specification). It's common to pass document as the context node.
- namespaceResolver
is a function that will be passed any namespace prefixes and should return a string representing the namespace URI associated with that prefix. It will be used to resolve prefixes within the XPath itself, so that they can be matched with the document. null is common for HTML documents or when no namespace prefixes are used.
- result
is an existing XPathResult to use for the results. null is the most common and will create a new XPathResult
- resultType
is an integer that corresponds to the type of result XPathResult to return. Use named constant properties, such as XPathResult.ANY_TYPE, of the XPathResult constructor, which correspond to integers from 0 to 9.
- xpathExpression
is a string representing the XPath to be evaluated.

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 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.
