// Package css provides the Chrome DevTools Protocol
// commands, types, and events for the CSS domain.
//
// 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.
//
// Generated by the cdproto-gen command.
