All test pass. Spot check on my personal site seems to be fine. Saves a whole 50 bytes minified, and 10 bytes compressed.
I left the odd "font-size: 1em" since I'm unclear exactly what this does. It's likely wrong (want rem) or un-necessarly or both, but this is enough change for this commit.
Comments welcome.
