Query: Not exactly complete, but a great reference regardless

This book is a terrific companion for web developers, whether beginning or experienced. I've worked with HTML for years, but there are always slightly more obscure tags that you just can't quite remember how to use, or the exact name of the tag. This is how this book comes in handy.In my opinion, it's not really all that complete in depth, but it is rather complete in breadth. By that I mean to say that if you need a tutorial, you may want other more in depth materials on the topic you're learning, such as cascading style sheets. But once you've done something once, and you just need a refresher, this book is a handy reference guide.
