47/**
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>.
