Reviews of HTML, XHTML, and CSS, Sixth Edition, Visual Quickstart Guide
Here are a few individual sites with reviews:
From Coderanch: It is easy to see why this is a popular web design book. Topics are laid out in a no-nonsense manner that makes everything look easy and achievable, there is plenty of content without being heavy, and the layout provides the flexibility for colored examples and additional points of interest.
From Terri Wells at devarticles.com: Earlier editions of the book sold more than a million copies, and it's easy to see why.
From WebSiteTips: She explains everything in easy-to-understand language, covers all the important bases of HTML, XHTML, and CSS, provides tips and warnings, and helpful illustrations and examples throughout the book.
From Ebookee: Of course, Elizabeth Castro manages to write books that not only speak to those who are already fluent in HTML, but are good for newbies too. She makes it a breeze to create sites that are visually stylish and technically sophisticated without the expense of buying an editor.
