+Changed css background-image property to img tag.
-Question: when the image was a background property it wouldn't work
unless I used ".jpeg" however, when I changed it to an image tag it
required a  ".jpg".  Am I hallucinating this, or is the "e" in jpeg/jpg
contingent on how the file is called?
+Moved links to Google fonts from body to head.
+Renamed classes to be more specific.
+Removed html from normalize.css Wade provided.
+Equalized column heights by changing body and main_content background
colors.
