Query: A great book on XHTML

Most people would say that this book is just a review of how to write proper HTML 4.0. DUH! Basically, that is what XHTML is. It is simply how to write "well-formed" HTML pages. This book will tell you how to write well-formed pages. In doing so, it fulfills its purpose.I liked this book because it lets you know about the importance of XHTML compatibility. It also tells you what the differences between HTML and XHTML are.Overall this is a great book. I would recommend it to the following people:People with pages wanting to make them compatible with the future.People wanting to learn how to write proper HTML.All webmasters.Well, thats that. Thanks for your time.
