val CSS: CSSOperations (source)
This domain exposes CSS read/write operations. All CSS objects (stylesheets, rules, and styles)
have an associated id used in subsequent operations on the related object. Each object type has
a specific id structure, and those are not interchangeable between objects of different kinds.
CSS objects can be loaded using the get*ForNode() calls (which accept a DOM node id). A client
can also keep track of stylesheets via the styleSheetAdded/styleSheetRemoved events and
subsequently load the required stylesheet contents using the getStyleSheet[Text]() methods.
This API is marked as experimental in protocol definition and can change in the future.
