I want to learn HTML5, where can I start?

The basics are the first to learn HTML well. CSS, Javascript, JQuery.
Where HTML5 is primarily a scripting program for HTML control +javascript.
       It is recommended to learn HTML  CSS and JavaScript (usually together) before looking at HTML5. This kind of books is still a lot, and most of them are similar.
It is important that the  Canvas object with the 2D drawing is HTML5
I think learning HTML5 need to first understand what is HTML start
HTML is hypertext
And this text page is a specification
After the understanding
Learn from the basics of HTML and don't learn HTML5 from the start
Because now the web is basically HTML4.
The 5 version is a new addition to the 4 base, and a stricter closure standard using XHTML
So learn HTML4 come faster, and then go deeper
1. Understanding HTML
2. Learn the syntax of HTML
3, their own simple use of HTML to create a Web page
At the end of the beginning to learn JS, Js=javascript scripting language
Learn DOM, XML Dom
