This book can serve two audiences. The first group consists of those who are just coming into Web design or have traditionally relied upon design tools to create Web sites and for the first time want to learn how everything under the hood works. The second audience is composed of designers who know HTML and have even written it by hand extensively but are now looking to learn the new XHTML specification, either as an end in itself or as a step toward working with XML. Both the novice and the experienced designers should come away from this book with new knowledge and techniques to incorporate in their design arsenal.
