I like 960 as an easy way of doing the layout of web sites. However, I'm not sure of it's capabilities.
I want to have a grid with 2 columns (grid_4) and 2 rows on the main part of my page and a column on the right (grid_4).
Is it possible to define a first grid of 8 colums and a second of 4 columns and then to put other cells inside the first column?
The pseudo structure:
grid_8
>grid_4
>grid_4
grid_4
The main idea is to have the last column with a different height of the main grid.
