grids - vertical split
- The problem is simple. When I create a nested grid, I want to be able
to have a single column below a grid... let me visualise:
First, I created a 3/4 - 1/4 split (c). Then, I split the bigger part
into two columns - a and b. How and where do I put the div that holds
d? I tried several things, but they either mess up everything or look
quite dirty (and don't render 100% nicely).
