XHTML Links and Resources

XHTML (eXtensible HyperText Markup Language) is a reformulation of HTML 4 as an XML 1.0 application. Together with CSS2, XHTML provides further support for separation of content and style. However, XHTML is a stricter language than its older brother, HTML, and requires the author to compose well-formed documents.
