Add spaces between panels in Bootstrap 3

Question

I'm using Bootstrap 3.0 and can't seem to figure out how to add padding / space between panels.

<div class="row">
  <div class="col-xs-4 panel">
    <div class="panel-body">
      <h4>First Cell</h4>
    </div>
  </div>
  <div class="col-xs-4 panel">
    <div class="panel-body">
      <h4>Second Cell</h4>
    </div>
  </div>
  <div class="col-xs-4 panel">
    <div class="panel-body">
      <h4>Third Cell</h4>
    </div>
  </div>
</div>

I have tried adding a class and setting the width to 30% but it only works if you have two panels and pull the one right. If I add a margin then it throws the responsiveness off and the last cell drops to the next line.

How can I responsively add a gap between the panels?

Answer 1

I'd be inclined to not combine .panel and .col*:

        </div>
    </div>
    <div class="col-xs-4">
        <div class=" panel">
            <div class="panel-body">
                 <h4>Second Cell</h4>

            </div>
        </div>
    </div>
    <div class="col-xs-4">
        <div class=" panel">
            <div class="panel-body">
                 <h4>Third Cell</h4>

            </div>
        </div>
    </div>
</div>

change the html like below,

      </div>
    </div>
    <div class="col-xs-4">

        </div>
    </div>
