Bootstrap reduce spacing between columns

css, html, twitter-bootstrap

Solution

The problem seems to be with the padding not the margin. This piece of css removes the white space between the columns

   .form-group .col-xs-6{
      padding: 0px;
    }

Problem

Having an issue reducing the amount of spacing between buttons in the same row. These buttons are wrapped in columns JSFiddle Is there an easy way to do this? I imagine using negative margins or padding is not necessarily desirable.
