Getting to grips with CSS

Overview

There are many developers who can't stand working with CSS, but are occasionally forced to, and many site administrators who are asked to make small changes to a site's design, but don't know where to start. This session aims to cover the basics of CSS and how to use it to make alterations to your site's theme.
If there's interest, I'll follow up this session with a BoF to help tackle specific problems on your own sites.
Please let me know if there's something I've missed from the agenda.
