UIkIt vs. Pure vs. Topcoat

UIkit gives you a comprehensive collection of HTML, CSS, and JS components which is simple to use, easy to customize and extendable.

Pure is meant to be a starting point for every website or web app. We take care of all the CSS work that every site needs, without making it look cookie-cutter.

TopCoat is made up of base controls, platform specific styles, themes and a build script to stitch them all together.
