This is a pretty good style guide and has a lot of habits I&#x27;ve been practicing for many years now (even pre-sass&#x2F;less).<p>Slightly off topic, I&#x27;m slightly bothered by the amount of trash talk CSS receives since it&#x27;s pretty much the best language we&#x27;ve ever had to define interface styles, and it&#x27;s only getting better. Maybe some of the rules about behavior are arguable, but by and large I&#x27;ve never met a design I couldn&#x27;t get to work with some well-defined CSS.<p>And if you can&#x27;t read nested CSS I can&#x27;t imagine how you&#x27;d feel in the face of some heavy XML.
