HTML5 for Web Designers
There have been many changes in the last few years with the emergence of browser support for html5 and css3 - these books provide insight to what can be put to use right now while keeping things backwards compatible.
I particularly liked the the usage of the <header> & <footer> tags. As well as a handy mention of a script that allows newer html5 tags to work in older versions of IE. Happy developing!
