Add sass conversion of css project file

Preliminary conversion to sass... strange errors resulting from media query section, wasn't sure why so for simplicity purposes I removed that section. Still not entirely sure when it's appropriate to use a mixin versus extend, it seems mixins are more for things that involve "mathish" calculations and I couldn't really find a spot in the doc where that seemed necessary; I included one in there just to make sure it was included but I'm not convinced it is the proper usage, will continue to work on this.
