Module cdp::css

[Experimental] 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.
