[Cc-webedit] Style guide

[Jon Leighton]

Hi all,

Alistair and I brainstormed stuff for a style guide a while back. I have
now typed up our notes here:

https://we.riseup.net/cc_website/style-guide

Please give thoughts/comments. Feel free to dive in and make edits and
then write a comment explaining what you changed.

I will also produce a page which has examples of all the different types
of elements and styles etc, along with illustrative examples ("don't do
this, do this, etc.").

Jon
