I'm just getting started with the fluid grid in CS6 but need a bit of help. I'm set up with 12 columns and the default desktop width is 1232px according to the options box. I don't want the grid to be 100% wide. In fact I want it no bigger than 960px at its max width. That works out to be approximately 78% (77.9) of 1232px. However, if I choose 78% as my width and drop in a DIV to span the whole 12 columns, it is far greater than 960px wide. What am I doing wrong and what do I need to do in order to have a starting width of as close to 960px as possible.
Any help is appreciated.
