Introducing Google Doctype
In its current (beta) form, Google Doctype contains dozens of articles written by top Googlers on topics important to all Web developers: security, performance, caching, DOM manipulation, CSS styling, and more. It contains over 8,000 lines of JavaScript code: Google’s own battle-tested JavaScript library, released today under a liberal open source license. And it contains the beginnings of a test-driven reference of the open Web: a reference of every element, every attribute, every DOM method, every CSS property, all backed up by test cases.
