CSSStyleSheet.cssRules
    Returns a live CSSRuleList, listing the CSSRule objects in the style sheet.
    This is normally used to access individual rules like this:
       styleSheet.cssRules[i] // where i = 0..cssRules.length-1
    To add or remove items in cssRules, use the CSSStyleSheet's deleteRule() and insertRule() methods, described below.
