Reading CSS at BBC Sport (Part 1) lead me to this presentation by Harry Roberts and then to CSSWizardry on GitHub.

Roberts also has created some basic components including the “nav” abstraction and, of course, Nicole Sullivan started all of this with back in 2010 with the media object

The BBC Sport article also talks about BEM which I’ve never really embraced but this might help me along.

Update: 06/21/16 Also found this book titled “Scalable and Modular Architecture for CSS” which serves as a good intro with some examples.
