CSSStyleSheet class
The interface represents a single CSS stylesheet, and lets you inspect and modify the list of rules contained in the stylesheet. It inherits properties and methods from its parent, StyleSheet.
StyleSheet
CSSStyleSheet
A stylesheet consists of a collection of CSSRule objects
representing each of the rules in the stylesheet. The rules are
contained in a CSSRuleList, which can be obtained from the
stylesheet's cssRules property.
For example, one rule might be a CSSStyleRule object
containing a style such as:
h1, h2 {
font-size: 16pt;
}
Another rule might be an at-rule such as @import or @media,
and so forth.
See the Obtaining a StyleSheet section for the various ways a
object can be obtained. A object can also be directly
constructed. The constructor, and the CSSStyleSheet.replace(),
and CSSStyleSheet.replaceSync() methods are newer additions to
the specification, enabling Constructable Stylesheets.
