title: How can I position this fontawesome icon vertically aligned in the middle of the header div in bootstrap
body: <p>I have a search filter box in a collapsable component in bootstrap.</p>
  
  <p>The markup is as follows:</p>
  
  <pre><code>&lt;div class="container"&gt;
  &lt;div class="col-xs-6"&gt;
  &lt;div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true"&gt;
    &lt;div class="panel panel-default"&gt;
      &lt;div class="panel-heading panel-heading-pointer" role="tab" id="headingOne" data-toggle="collapse" href="#collapseOne" &gt;
        &lt;h4 class="panel-title"&gt;
  
        &lt;/h4&gt;
            Search Filters&lt;span style="padding-bottom:10px"&gt;&lt;i class="fa fa-arrow-circle-down fa-2x floatRight"&gt;&lt;/i&gt;&lt;/span&gt;
  
      &lt;/div&gt;
      &lt;div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne"&gt;
        &lt;div class="panel-body"&gt;

      &lt;/div&gt;
    &lt;/div&gt;
    &lt;/div&gt;
    &lt;/div&gt;
    &lt;/div&gt;

  <p>The output of this looks like:
  <img src="https://i.stack.imgur.com/aFiyW.png" alt="enter image description here"></p>
  
  <p>I would like the fa-arrow-circle-down icon to be sat in with equal spacing at the bottom and top of the header div - such that it is sat in the middle of the header - like the text. I have tried adding margins, spans, paddings, but nothing seems to shift up the position of the icon!</p>
  
  <p>Please help!</p>
  
  <p>The only custom style I have is the floatRight which is :</p>
  
  <pre><code>.floatRight{
      float:right;
  }
  </code></pre>
  
  <p>Many thanks!</p>
