To expand on @isherwood’s answer, here is the complete code for creating custom -sm-
widths in Bootstrap 3.3
In general you want to search for an existing column width (say col-sm-3
) and copy over all the styles that apply to it, including generic ones, over to your custom stylesheet where you define new column widths.
.col-sm-3half, .col-sm-8half {
position: relative;
min-height: 1px;
padding-right: 15px;
padding-left: 15px;
}
@media (min-width: 768px) {
.col-sm-3half, .col-sm-8half {
float: left;
}
.col-sm-3half {
width: 29.16666667%;
}
.col-sm-8half {
width: 70.83333333%;
}
}
