An object implementing the CSSStyleSheet
interface represents a single CSS style sheet.
A CSS style sheet consists of CSS rules, each of which can be manipulated through an object that corresponds to that rule and that implements the CSSRule
interface. The CSSStyleSheet
itself lets you examine and modify its corresponding style sheet, including its list of rules.
In practice, every CSSStyleSheet
also implements the more generic StyleSheet
interface. A list of CSSStyleSheet
-implementing objects corresponding to the style sheets for a given document can be reached by the document.styleSheets
property, if the document is styled by an external CSS style sheet or an inline style
element.

property will return that CSSImportRule
, otherwise it returns null
