This is a pretty good style guide and has a lot of habits I've been practicing for many years now (even pre-sass/less).
Slightly off topic, I'm slightly bothered by the amount of trash talk CSS receives since it's pretty much the best language we've ever had to define interface styles, and it's only getting better. Maybe some of the rules about behavior are arguable, but by and large I've never met a design I couldn't get to work with some well-defined CSS.
And if you can't read nested CSS I can't imagine how you'd feel in the face of some heavy XML.
