It's not i'm stupid or something (or maybe I am :o), how do I change the font size for normalize.css? It's too big for the layout I'm making and I've seen they're using **percentage** for the font size. Will changing the font-size of `html` directly affect the font-sizes of all child elements or I'd have to calculate too to decrease the font-size of all the other elements?

**EDIT**: [Normalize.css](http://necolas.github.com/normalize.css/2.0.1/normalize.css) is over here.
