Detailed Description

This class provides the glue between HTML parser and CSS subsystem.

It maintains a document tree and creates and caches style objects for use by the HTML parser. The HTML parser in turn informs StyleEngine about opened or closed HTML elements and their attributes via the startElement() / endElement() methods.
