I tweaked it to get the header & border to work on 4.1.8

<!-- Your Block -->

<div id="wgo" class="collapse wgo_block block">
  <h2 class="blockhead">Your Block Title Here</h2>
  <div class="blockbody formcontrols floatcontainer">
    <div class="wgo_subblock">
      <div>

<!-- Your Code Here -->

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

<!-- end Your Block -->
