Query: Everything and Out of Date

This books takes a very progressive look at HTML and then shows how XHTML differs at the end. If there is a tag or attribute, whether valid or not, this book covers it in enough detail to quench any web author's needs. I already had a firm grasp on HTML, but I learned a few new things throughout the book (I read it cover to cover). My only complaint is that it is a little outdated. It also dedicates a whole chapter to unused tags (a bit much), but it nice to know about these things. It gives a very good tour of CSS and forms. Good as a reference.
