Updates Color Code interaction and minor site adjustments.

- Site is now using a 14 column grid: 2 for the nav, 10 for the content, plus 1 column on each side of the content as margins. A 16 column grid was resulting in very narrow columns, which in turn were rendering a very small logo, so this was the best alterative I could find.

- Revised content alignment for sections 2, 3 and 4.

- Testing new HTML structure for section 4, which is currently not working 100% correctly.

- Using an unholy CSS to make the Color Code interaction animation with 100% CSS.

- The above item was crazy hard to do

- Found out float: center is exactly the same as float: redballon
