Woohoo! We're getting SOOOO close. That last bit worked (!!!), and I've got a GoodReads icon in the TopBar and Footer. I had to massage the CSS a little to get it lined up properly, and sized correctly, but it's there!
However...the color doesn't match. Can that be done dynamically, or do I need to do it in Photoshop, or something?
And, while I'm asking, how would I dynamically size/resize this icon?
