Quoted from O'Reilly:
HTML: The Definitive Guide, second edition, is a complete guide to creating documents on the World Wide Web. To become a true master of HTML, you need to develop your own style. That means knowing not only what's appropriate, but what's effective. This book describes basic syntax and semantics and goes on to show you how to create beautiful, informative, and dynamic web documents you'll be proud to display. HTML: The Definitive Guide helps you become fluent in HTML, fully versed in the language's syntax, semantics, and elements of style. The second edition covers the most up-to-date version of the HTML standard (the proposed HTML version 3.2), Netscape 4.0 and Internet Explorer 3.0, plus all the common extensions, especially Netscape extensions. The authors cover each and every element of the currently accepted version of the language in detail, explaining how each element works and how it interacts with all the other elements. They've also included a style guide that helps you decide how to best use HTML to accomplish a variety of tasks, from simple online documentation to complex marketing and sales presentations.
