CSS - Fundamentals Of Css

hi.

looking for a good book to learn css, which does *not* labor ie6 hacks, since none of my readers use ie6 any longer.

i have read the head first book on xhtml/css, and now looking to expand my knowledge on css to include strong fundamentals, so i can move onto more cutting-edge stuff.

a friend recommended css mastery, but this book was published in feb 2006, and ie7 was released nov 2006, so i don't see how it could be considered applicable to current browsers.

there are so many to choose from.

again i'm looking to learn strong fundamentals, without the need to spend time learning ie6 hacks.

thanks.
