Create character page -RFR

Set up CSS for the characters show page. All of our tests pass except for the ones created by Henry and Joe (which will be fixed upon the merge) and one test fails due to the eval. Seeing that this appear to be a problem according to Hound as well, I am wondering if this is something that needs to be changed. 
Prefer double-quoted strings unless you need single quotes to avoid extra backslashes for escaping.
