Possible to control vertical source ordering with 960 Grid System?

I've understood it's possible to control the horizontal (columnwise) source ordering with the 960 Grid System. However, is it possible to do something similar vertically?

If not, does anyone know of any grid system that handles source ordering 开发者_如何转开发vertically?

Thanks, Jens

Are you looking for a grid system (css framework) with both horizontal and vertical control?

Few days ago I tried #grid and I think it does what you are looking for
