Unlike basic HTML guides, this book is crafted for web designers and developers who have already gained a working familiarity with the basics of HTML and web design. These advanced users want to take their markup further, making it leaner and more semantically rich, for more efficient, more usable and accessible web sites. HTML Mastery does all this and more, discussing and demonstrating all available HTML tags, including less common ones. The book explains where and how to use them, and offers styling and scripting techniques that can be employed in sophisticated web sites. In addition, the book also explores some of the advanced semantic tools that look to further improve the usability and semantic value of sites. HTML Mastery devotes an entire chapter to Microformats, and gives the reader a preview of XHTML 2.0 and Web Applications 1.0 — web standards of the future.
