tab traversal orderXHTML stands for eXtended HyperText Markup Language. You can use it to build pages on the World Wide Web. XHTML is a refinement of HTML, the original language of the Web invented by Tim Berners-Lee in the early 1990s.
This document is a quick reference for XHTML 1.1. Not every feature is covered, just the features that most people will need most of the time. For the exact definition of the language, see the XHTML 1.1 Recommendation at the World Wide Web Consortium (W3C) web site.
If you would like to check your page for validity, the W3C Consortium maintains an online validator for XHTML.
