This Definitive Guide is an O'Reilly classic. It covers every element of HTML & XHTML in detail, explaining how each element works and how it interacts with other elements. With hundreds of examples, this book shows readers how to create effective web pages, how to master advanced features like Cascading Style Sheets, and how to take effluent out of the popular WYSIWYG tools like Frontpage and Dreamweaver. The latest edition is updated to cover Internet Explorer 7, Firefox 1.5, HTML 4.01, XHTML 1.0, CSS2, and a preview of XHTML2 and CSS3. One of the real value-added features of the "Definitive Guide" format is a comparison of which technologies the various browsers support and which they don't. This edition includes a review of the newer initiatives in XHTML (XForms, XFrames, and modularization), and covers the essentials on XML for advanced readers.
