Just to add to the raves - this is the most useful reference book I own. I have two copies so I can have one at home and one at work. It has everything you'll ever need for HTML, Javascript and CSS, never mind the usefulness of the Dynamic HTML sections.

The one complaint I have is that it's time for a second edition, to cover IE5 and 6 and the Mozilla-based Netscape 6 family. But, since this edition already includes some DOM 1 information it is still extremely useful in its current form.
