XHTML, which stands for Extensible Hypertext Markup Language, is HTML defined as an XML application. As such, XHTML is a markup language that is similar to HTML but is stricter and expands its capabilities. Web pages that follow the syntax rules of XHTML are said to be "well-formed." XHTML became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000 and it aims to replace HTML. XHTML is now a Web standard.

CSS, which stands for Cascading Style Sheets, was developed by the W3C. CSS allows full control over HTML by styling the HTML files, using various formatting features, graphics, etc. Consequently, web developers can separate the design of a Web site from its content.

Comparing XHTML and CSS, one could say XHTML structures the Web page while CSS styles it.
