I am a "beginner" in dhtml. Ok i know some javaScript and some HTML, which is what DHTML is anyway! I was advised by a friend not to buy this book, but, for a tenner, i thought, why not? This book is great, because it has a very in-depth section/s on CSS and CSS-P, which involves the various aspects of CSS (text,margins etc) and also goes into some detail about positioning etc. The reason why this book is not getting 5 stars from all the reviews is either the person wants £50 worth of book for £10 or simply the said person has not read and understood the book. This is by no means an exhaustive supply of DHTML comcepts and i would recommend "Javascript in a week/21 days" by SAMS and "DHTML Magic" by Jeff Rouyer to finish your course. This is a great book for beginners and for the internmediate, buy it!
