| This interface represents a document with a CSS view.
The getOverrideStyle method provides a mechanism through
which a DOM author could effect immediate change to the style of an
element without modifying the explicitly linked style sheets of a
document or the inline style of elements in the style sheets. This style
sheet comes after the author style sheet in the cascade algorithm and is
called override style sheet. The override style sheet takes precedence
over author style sheets. An "!important" declaration still takes
precedence over a normal declaration. Override, author, and user style
sheets all may contain "!important" declarations. User "!important" rules
take precedence over both override and author "!important" rules, and
override "!important" rules take precedence over author "!important"
rules.
The expectation is that an instance of the DocumentCSS
interface can be obtained by using binding-specific casting methods on an
instance of the Document interface.
