How to remove space between dt and dd in Bootstrap horizontal description

How can I remove the gap/space between dt and dd in bootstrap Horizontal description?

As you can see from following image there is a big space between dt and dd (highlighted in yellow)

I tried to set the dt cell value by using

.dl-horizontal dt {
 width:100px;
 }
.dl-horizontal dd {
 width:100px;
 }

but the property just changed the text size! and the cell remained at the same size and position.

This should do the trick:

.dl-horizontal dd {
    margin-left: 120px;
}
