HTML 5 Cheat Sheet (PDF) - Smashing Magazine
XHTML 2 is dead, long live HTML 5! According to W3C News Archive, XHTML 2 working group is expected to stop work end of 2009 and W3C is planning to increase resources on HTML 5 instead. And even although HTML 5 won’t be completely supported until 2022 , it doesn’t mean that it won’t be widely adopted within the foreseeable future. So in the spirit of the upcoming change we decided to release a handy printable HTML 5 Cheat Sheet that lists all currently supported tags, their descriptions, their attributes and their support in HTML 4. Please notice that the specification is an ongoing work, and is expected to remain so for many years, although parts of HTML 5 are going to be finished and implemented in browsers before the whole specification reaches final Recommendation status. We’ll do our best to update the cheat sheet when new changes will become known.HTML5
