[pcupp] What's the goal of the sub-cell(do you mean sub-column)/row syntax?  In general the grid-template property can only express a subset of the layouts that are possible with the grid, so I see its utility purely as a means to visualize the grid you are trying to create.  I have a tough time seeing how the two template definitions above are equivalent, so IMO it fails the "easy to visualize test".
