Document (Document Object)
The Document provides access to the contents of the HTML document currently loaded. In
early browsers, this was primarily a browser object because there was no standard governing
its structure. With the rise of the DOM, this object has become standardized, although modern
browsers continue to provide a multitude of proprietary features.
HTML elements in the page are represented as objects under the Document. Each such
element object has properties and methods derived from a variety of sources. The most
obvious of these are proprietary browser features, but elements also inherit properties and
methods from the DOM Node interface, the DOM HTMLElement definition, and possibly more
specific DOM objects. While the specific origin of a property is often not particularly important
so long as the property is well supported, the reader should be aware that the structure of each
element object is derived from a variety of sources.
The collections contained within the Document are in general read-only, although specific
elements of the collections are often mutable.
Properties
activeElement Reference to the object related to the element that currently has focus.
This property is read-only. (IE4+)
alinkColor String containing the color of activated links. (IE3+, MOZ, N2+, DOM0)
anchors[] Collection of Anchor objects in the page (corresponds to ...). The collection is read-only, though the individual anchors can be
modified and the DOM can be used to directly add or remove anchors that will
ultimately affect the array‘s contents. (IE3+, MOZ, N2+, DOM1)
applets[] Collection of Applet objects in the page (corresponds to elements).
Like other document collections the individual objects can be manipulated, though the
array itself is read-only. (IE4+, MOZ, N3+, DOM1)

DOM0)
body Reference to the or element object of the document. (IE3+,
