Personal best practices

Good code! Very readable aswell. Half the CSS-stuff I read is cluttered like hell. Let's get to the point, though:
- Using custom font's is great, of course. But I would provide the user some fall-backs. Custom fonts have a history of being ridiculously annoying on the web, so using fonts that EVERYONE has is highly advisable.
- Personally, I would stick with either using EM or PX - not both at the same time. But hey, everyone has their own thing. ;-)
