“Considered the standard text on the subject of HTML and XHTML, this up-to-date volume provides a good mix of tutorial and reference. It is an essential guide for any serious user of hand-coded Web sites, as well as a comprehensive introduction for the novice. Advanced subjects include Cascading Style Sheets (CSS3), XHTML2, XForms, XFrames, Java applets, JavaScript programs, and much more.”

“If you do web development, you should have one solid HTML/XHTML reference guide on your bookshelf. This one ranks up there... HTML & XHTML: The Definitive Guide (6th Edition) by Chuck Musciano and Bill Kennedy. Although the CSS and XML sections are a little light, the core HTML and XHTML information is all you could ask for...This book does a good job in blending a bit of tutorial information with a lot of reference material. All the HTML tags that exist are documented, along with whether it's an extension/deprecated/archaic, what type of browser support is involved in using the tag, and all the attributes and locations where it can be used...this is a book that I'll want to keep around for those strange times when my HTML tags just aren't working like they're supposed to.”

“Calling this book "The Definitive Guide" is not a misnomer, for that's what it is...Weighing in at over 600 pages means that if it ain't described in here you probably shouldn't be doin' it! And if it is described in here, it's described clearly and accurately. As always, thanks a bunch. I am so much smarter (yeah, right) thanks to you guys! ”

“I was surprised by the format of the book, however I do think it is a good resource for HTML/XHTML. While it is "The Definitive Guide" covering all of the markup tags and attributes it is definitely not a Cookbook or Nutshell book. I would recommend this book to those looking for a reference that is detailed and in a dictionary type format.”
