//! 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.
