5,020 PointsCould you further explain the omega class?
I did not conceptually pick up on what the omega class does and when it should be used. Could you explain this further?

20,597 PointsOmega helps remove margins on the right of a grid item its basically what you use when all your html cols add upto 12 without it would push elements underneath one another rather than keeping a consistent vertical alignment

39,199 PointsThe "alpha" class is used on the FIRST "child" div. It shifts the div to the left to make it line up with your design.
The "omega" class is used on the LAST "child" div. It shifts the div to the right to make it line up with your design.
