Is the HTML 5 Spec already complete?

I'm was looking for an HTML 5 and CSS 3 framework, I found 52Framework but I've noticed that a lot of HTML 5 elements are still missing, even at开发者_StackOverflow the most basic level (reset.css).

I though of making my own framework but I need to know if the HTML 5 standard is already complete or if it's still subject to changes, I Googled a bit but couldn't find any clear answer.

Does anyone know? Thanks in advance!

No, but you can still use aspects of it. See When will HTML5 be finished? for details.

According to this WHATWG FAQ:

"Finished" is a big deal... You'll be able to use HTML5 long before then. See When will we be able to start using these new features?

It is estimated by the editor that HTML5 will reach the W3C Candidate Recommendation stage during 2012. That doesn't mean you can't start using it yet, though. Different parts of the specification are at different maturity levels. Some sections are already relatively stable and there are implementations that are already quite close to completion, and those features can be used today (e.g. <canvas>). But other sections are still being actively worked on and changed regularly, or not even written yet.

Per the spec, it's still a working draft as of last month, so there can and will be changes to the spec as it develops. I'm guessing many of the elements that we know and use right now are here to stay though :)

I would say its still work in progress.

Here are Ian Hickson’s estimates/guesses on when the HTML5 spec will be “complete”:

2012 - W3C Candidate Recommendation

2022 - W3C Recommendation (but see http://wiki.whatwg.org/wiki/FAQ#When_will_HTML5_be_finished.3F for the tough criteria required for HTML5 to become a recommendation.)
