Best lightweight CSS framework for simple responsive websites?

Question

I recently ran into Skeleton CSS and loved it. What are your favourite lightweight frameworks?

James Welch · Accepted Answer

I've really enjoyed using purecss.io on my projects and even built it into a CMS tool that I made. It's a lighter option than bootstrap and I find it has 99% of the things I need out of the box.

Easier to learn, and easier to use than other CSS frameworks.
