I'm confused by this. The description says that the children don't need to add up to amount of the parent column, but the example below looks exactly the same as the fixed grid example. Fixed grid uses 3+3 inside of a 6. Fluid uses 6+6 inside of a 12. They seem to function the same even the description says they are a bit different.
