Nick didn't make it especially clear why the <div> elements needed to be classed "omega". If I've understood it right, 12 x (65 grid width + 20 gutter width = 85) = 1020 px means that you need to remove the margin-right 20 px value so that it all fits into the 1000px width? Is this correct?

Used to ensure the classes element is aligned to it's respective margin.
