W3C
The World Wide Web Consortium (W3C) is an international consortium developing standards for the Web and providing validation against some of those standards.
There are two W3C tests on these pages, one for XHTML 1.0 Strict because there is no reason to use anything less on your Web site, and CSS level 2 because most commonly used browsers support the useful parts of CSS 2.
