title: Bootstrap accordion with chevron icon has a little bug
body: <p>Thanks to this <a href="https://stackoverflow.com/questions/18325779/bootstrap-3-collapse-show-state-with-chevron-icon">SO question</a> and this <a href="https://stackoverflow.com/questions/19236717/how-to-make-bootstrap-accordion-collapse-when-clicking-div">SO question</a>, I have been able to create a Bootstrap accordion with</p>
  
  <ul>
  <li>A fully clickable header for each panel</li>
  <li>Chevron arrows on the right indicating the state of a panel</li>
  </ul>
  
  <p>Now, I noticed a little bug when expanding/collapsing a panel: the content on the far right side of the expanding/collapsing panel is pushed to the left a little during the animation, and suddenly jumps to its normal position when it's complete.<br>
  I'm guessing it has this behaviour because of the float attached to the chevron icon.</p>
  
  <p>I've created a <a href="http://jsfiddle.net/3gYa3/221/" rel="nofollow noreferrer">JSFiddle</a> demonstrating the problem, and here's the code:</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;div class="panel-group" id="accordion"&gt;
      &lt;div class="panel panel-default"&gt;
          &lt;div class="panel-heading accordion-toggle" data-toggle="collapse" data-parent="#accordion" data-target="#collapseOne"&gt;
               &lt;h4 class="panel-title"&gt;Item #1&lt;/h4&gt;
  
          &lt;/div&gt;
          &lt;div id="collapseOne" class="panel-collapse collapse in"&gt;
              &lt;div class="panel-body"&gt;Content #1&lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      ...
  &lt;/div&gt;
  </code></pre>
  
  <p><strong>CSS:</strong> (did I mention I used a pure CSS solution?)</p>
  
  <pre><code>.panel-heading.accordion-toggle:after {
      font-family:'Glyphicons Halflings';
      content:"\e114";
      float: right;
      position: relative;
      bottom: 23px;
      font-size: 15pt;
      color: grey;
  }
  .panel-heading.accordion-toggle.collapsed:after {
      content:"\e080";
  }
  </code></pre>
  
  <p>I'm sure it's just a little thing, but I can't seem to find it.</p>
