Top of page
Copy this block at the top of your page. Replace LEFT HEADER and RIGHT HEADER as appropriate. If you're using a color code, remove the comment lines around that block; if not, you might want to remove the whole block.

Fill in commentary/comparison
Now go back through, and in the empty lines, fill in your comparison or commentary. The right side bits go after the left side bits. If you're using color codes, fill in the color on the "background-color:" bit; if not, it's okay to leave that as-is.
