If you¿re a web developer who has worked with HTML, you will find much of XHTML instantly familiar and readily usable. However, there are parts of XHTML that are derived from XML, which may be unfamiliar and perhaps a bit harder to understand. In XHTML, Chelsea Valentine and Chris Minnick provide the explanations and explorations that will help you become familiar and comfortable with the "X" in XHTML. XHTML addresses the need of working Web professionals to learn what XHTML is and how best to use it, and helps those who are contemplating making the switch from HTML to XHTML decide if and when to take the plunge. Both the authors not only write about and teach XHTML, but also consult and implement this technology as part of their workday routines. They¿ve learned from their audiences and students what people most need to know, and what examples and illustrations best illuminate that information. That collective wisdom drives this book throughout.
