If you want to do an offset bootstrap style you need to add this to your grid.css file:
.offset_11 { margin-left: 91.46% !important; }
.offset_10 { margin-left: 83% !important; }
.offset_9 { margin-left: 74.54% !important; }
.offset_8 { margin-left: 66.08% !important; }
.offset_7 { margin-left: 57.62% !important; }
.offset_6 { margin-left: 49.16% !important; }
.offset_5 { margin-left: 40.7% !important; }
.offset_4 { margin-left: 32.24% !important; }
.offset_3 { margin-left: 23.78% !important; }
.offset_2 { margin-left: 15.32% !important; }
.offset_1 { margin-left: 6.86% !important; }
Then add the offset class to the column you want to offset. For example:
<div class=”col grid_8_of_12 offset_2″>
(the !important overrides the .col:first-child { margin-left: 0; } for first columns)
