Thank you, for those fast answers. I think I’m going to stick with 30, 45 and 60em, if needed I could still change those values or add another one.

Sure there are many frameworks, but I couldn’t find one based on lesscss wich suits my needs. The idea is a modular (even mixins are modular) framework, where you just pick whatever you need.
