I needed a comprehensive, intelligent guide covering HTML, DHTML, CSS etc. This book provides that and more in a easy to understand manner, that isn't too simplistic for an advanced web author. A smart layout, and nice index helps you locate what you need fast. Color charts, CSS style references, tag attributes a-plenty, DHTML overviews and in-depth information is there when you need it. If you're looking to spend on a clever guide to take you into the ever expanding world of web technologies, this book is a excellent resource!
Output:
Positive
