Billboard Layout

Noah, I've made some markup and css changes to create the text-overlay you showed in your design.

The css is easy to see, but the markup got messed up. The changes to pay attention to are on [line 163](https://github.com/mica-gd-431-kutil/project-01/compare/noahboyle:gh-pages...billboard#diff-eacf331f0ffc35d4b482f1d15a887d3bL163)

This is called a pull request on github. Read about [bringing my changes into your project](https://help.github.com/articles/merging-a-pull-request).
