Open source the front-end on GitHub

Last weekend I was part of the docsprint hosted at Adobe & the sfhtml5 user
group.
It was great seeing how many people added & updated documentation.

Since many people were developers, I noticed that some of them actually
wanted to update the site themselves:
 - Make it more accessible by adding aria roles
 - Deliver a better user experience by making it more clear which labels
belong to which select boxes. [1]
 - Adding syntax highlighting when you use "edit page". (this is different
from "edit" where you can do <syntaxhighlight language=""> but isn't
recommended)
 - (personal request) adding live examples (e.g. dabblet/JSBin) [2]. A
working video prototype at [3] and the code is at [4].

So wouldn't it be great if other people can contribute to this?
That's why I wanted to suggest to put the front-end code on GitHub. [5]

Some people already made comments to the ticket but I'm trying to figure
out how to actually make this happen.
