I am a code book whore and it is with this addiction that I have received a few new books over the holiday season. DOM Scripting by Jeremy Keith is a really good book on learning the ins and outs of DOM and JavaScipt. CSS Mastery is a book by Andy Budd and it goes over CSS tips and hacks but teaches proper usage and shows you how to do it correctly...this was a book we had a work until the owner moved away. My final Christmas book, and current read, is Bulletproof Web Design by Dan Cederholm. So far I'm 30% of the way through this one and it's a pretty good read...if your into CSS and XHTML and why you should do it properly...if not then go read something else. These are all good titles if you want to learn some CSS/JavaScript magic.
