How do you manage your stylesheets? - JayPanoz/Soma GitHub Wiki

I’m basically using LESS so that I can automatically compute vertical rhythm in em based on body’s font-size, line-height and a predefined modular scale.

This in-house tool is currently being extended into a CSS framework for eBooks. More about that soon.

For the record, the backbone of Soma’s styling was generated using v.0.66.6 of this framework.
