Looks good!

I created a similar alternative, Neat CSS, a while back. I use it for tons of projects. It could probably use a fresh look from me to see if there's anything I want to update but it's been a stable "framework" for me. I didn't intend it to be classless, though it's mostly semantic, but I instead focused on keeping it small and tight. It's only 3KB.

Anyway, thought I'd share it here too.
