    48  * This interface represents a document with a CSS view.

    49  * <p> The <code>getOverrideStyle</code> method provides a mechanism through

    50  * which a DOM author could effect immediate change to the style of an

    51  * element without modifying the explicitly linked style sheets of a

    52  * document or the inline style of elements in the style sheets. This style

    53  * sheet comes after the author style sheet in the cascade algorithm and is

    54  * called override style sheet. The override style sheet takes precedence

    55  * over author style sheets. An "!important" declaration still takes

    56  * precedence over a normal declaration. Override, author, and user style

    57  * sheets all may contain "!important" declarations. User "!important" rules

    58  * take precedence over both override and author "!important" rules, and

    59  * override "!important" rules take precedence over author "!important"

    60  * rules.

    61  * <p> The expectation is that an instance of the <code>DocumentCSS</code>

    62  * interface can be obtained by using binding-specific casting methods on an

    63  * instance of the <code>Document</code> interface.

    64  * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113'>Document Object Model (DOM) Level 2 Style Specification</a>.
