CSSStyleSheet.replace()

The replace() method of the CSSStyleSheet interface asynchronously replaces the content of the stylesheet with the content passed into it. The method returns a promise that resolves with the CSSStyleSheet object.

The replace() and CSSStyleSheet.replaceSync() methods can only be used on a stylesheet created with the CSSStyleSheet() constructor.

Inputs: text A string containing the style rules to replace the content of the stylesheet. If the string does not contain a parsable list of rules, then the value will be set to an empty string.

Inputs: Note: If any of the rules passed in text are an external stylesheet imported with the @import rule, those rules will be removed, and a warning printed to the console.
