There are a billion of these frameworks. This site allows you to compare a lot of them, though it does not yet include dev.css:

There's a lot of "classless" css frameworks.

Custom hand-rolled css will always be best, but when I need something fast I've been using the confusingly named purecss for years this since it's compartmentalised in such a way that you can just exclude the parts that you don't use (e.g. tables) to save on network size.
