How Browsers Work is an in-depth resource -- about 50 printed pages long -- explaining how a browser begins with HTML, CSS, and JavaScript files, and ends up with a display.

The clear explanation, based on FireFox and Chrome/webkit, explains many of the nuances that frequently cause edge-case bugs in CSS rendering or JavaScript code. It also provides a good introduction to parsing techniques (browsers use various kinds of parsers and parser generators), along with other lower-level implementation details.

The CSS 3 Selector specification defines pseudo-classes and pseudo-elements. QueryPath implements as many of these as is possible.

This is a draft reference that will probably be included in QueryPath 2.0. Read on to view the entire document.
