  19:  * This interface represents a document with a CSS view.
  20:  * <p> The <code>getOverrideStyle</code> method provides a mechanism through
  21:  * which a DOM author could effect immediate change to the style of an
  22:  * element without modifying the explicitly linked style sheets of a
  23:  * document or the inline style of elements in the style sheets. This style
  24:  * sheet comes after the author style sheet in the cascade algorithm and is
  25:  * called override style sheet. The override style sheet takes precedence
  26:  * over author style sheets. An "!important" declaration still takes
  27:  * precedence over a normal declaration. Override, author, and user style
  28:  * sheets all may contain "!important" declarations. User "!important" rules
  29:  * take precedence over both override and author "!important" rules, and
  30:  * override "!important" rules take precedence over author "!important"
  31:  * rules.
  32:  * <p> The expectation is that an instance of the <code>DocumentCSS</code>
  33:  * interface can be obtained by using binding-specific casting methods on an
  34:  * instance of the <code>Document</code> interface.
  35:  * <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>.
