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

<div class="col-lg-6">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 2 (center)
    </div>
   </div>
 </div>
</div>

<div class="col-lg-3">
 <div class="panel panel-default">
  <div class="panel-body">
    Panel 3 (right)
    </div>
   </div>
 </div>
</div>

</div>

<div class="row">
