Note, we'll probably want to write some introductory text on the main css-coding-styleguide.md page now, as it's now empty.

My only comment is if we could prefix the .md files with something like css_styleguide. So like css_styleguide-accordion.md. This is just for organizational reasons.

If it's difficult to do, I'm fine merging now because this looks so awesome.

Oh good call. Actually, I just learned it works to have them in their own folder, so I just did that.
