I bought this book to learn how to create a new menu system for a web site that I'm working on, and I certainly don't regret the choice. Danny Goodman's book does a very good job of covering Dynamic HTML (DHTML), HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), DOM (Document Object Model) and even JavaScript.
The amount of information in this book is incredible. 1400 pages!
Mr. Goodman explains the current situation, where Microsoft's Internet Explorer follows one "standard" and the other browsers follow the W3C standards to varying degrees. He also indicates which version of MS IE first began to support each feature, allowing you to decide whether you want to use some feature that some of your clients' older browsers may not support. This kind of information is invaluable if you want to make your web site cross-browser compatible, including support for Macintosh, Unix, Linux, etc., as well as Windows.
My only criticism is that the book is unfortunately becoming a bit dated. It was published in Sept. 2002 so it obviously can't contain any information about the latest versions of web browsers. On the other hand, Microsoft has not released any new version of IE for over two years, so it's only information about the latest versions of Netscape and other browsers that is missing.
One additional thing I liked about this book was that Danny Goodman sometimes uses an almost poetic English, something rather unusual in a technology book. A couple of examples from page 19: "... can be a challenge unto itself." "If the inexorable flow of new browser versions..."
Highly recommended if you are making web pages that require the use of Dynamic HTML.
