While at lunch today, we got on to the conversation of web design and web development resources.  I have sitting on my desk at all times, well, unless I'm using them at home:

• Cascading Style Sheets: The Definitive Guide by Eric Meyer
• Web Standards Solutions: The Markup and Style Handbook by Dan Cederholm
• Web Design Index 5 from The Pepin Press

I've got a few other books that I keep handy, though I'm noticeably missing an HTML book, and a copy of the W3C CSS 2.1 spec. 

I've got a few websites that I like to keep an eye on for resources, for example, color charts, HTML escape sequences, and such.

What about you, what are your favorite sites/books?  What's sitting on your desk?
