Update cookbook partial style

:fork_and_knife: 

From [this](https://trello.com/c/06QCB0Dr/153-update-the-style-and-content-of-the-cookbook-partial) Trello card. The Follow button in the WIP screenshot matches the existing style, but can change if need be. The icons aren't exact, but are as close as I could get with FontAwesome.
