The nice thing about Pure to me is the fact that they encourage you to write your own top layer. While Bootstrap 3 says that they also encourage this, the number of components in Bootstrap make it somewhat difficult to learn and implement.<p>An hour of looking at Pure, however, is enough to get started with confidence.<p>The grid classes are a bit strange to me though.<p>`pure-u-1-2` is "descriptive"? Not so much, unless you know the system.
