Wrap content after the ribbon in a `pure-u` to get around an Android bug

Chrome 29 on Android appears to have a bug with `display: inline-block`.
The bug does not exist on either Chrome 28 or 30 beta. The solution to
get around this is to make other things `display: inline-block` :(
Update Pure to v0.3.0-rc-2
