Working with grids video 6:00
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?
Yes this is the case .alpha will remove it on the first child and .omega will remove it on the last child.
Used to ensure the classes element is aligned to it's respective margin.
