 An HTMLDocument is the root of the HTML hierarchy and holds
the entire content. Besides providing access to the hierarchy, it also
provides some convenience methods for accessing certain sets of
information from the document.
 The following properties have been deprecated in favor of the
corresponding ones for the BODY element: alinkColor background
 bgColor fgColor linkColor vlinkColor In DOM Level 2, the method
getElementById is inherited from the Document
interface where it was moved.
See also the Document Object Model (DOM) Level 2 Specification.
