programming

I want to start to program and I noticed that it seems like HTML5 is going to become the next big thing.
Should I look into a book about HTML5 programming or do I need to go through all(HTML1, 2, 3, 4, 5) of them to be able to program on it?

There's a difference between “website programming” and “using HTML to markup a web page”. Website programming uses the power of programming languages to control the structure of the individual web pages that form a web site. HTML is a “markup language” that is NOT capable of solving any programming problem.
