This tutorial is designed for a college-level class in Web development. Language elements follow the latest XHTML (eXtensible HyperText Markup Language) standards published by the World Wide Web Consortium (W3C) and implemented by modern Web browser software. Extensive coverage of XHTML and Cascading Style Sheets (CSS) provides the language elements needed to compose most types of Web pages with the most common features.

The materials cover XHTML 1.1, the most recently published implementation of the language, now a subset of XML (eXtensible Markup Language). Many of the features of earlier versions of HTML and XHTML have been removed or replaced by newer methods of producing markup for structuring and styling Web pages. However, many of the language elements that are not supported under version 1.1 are presented here for compatibility with traditional methods; the student is likely to encounter these elements on existing pages, while adopted newer methods for future pages.
