body: <p>I would like to add an if statement to the below code that checks to see if the first element within the div (#content) is a H3 tag. </p>
  
  <ul>
  <li>If so, add the class (removeline) to the first H3 within the div. </li>
  <li>If not, do nothing.</li>
  </ul>
  
  <p>How would I got about adding this if statement to the following?</p>
  
  <pre><code>$(document).ready(function(){
      // Fix first Header tags in content
      $("#content h3").first().addClass("removeline");            
  });
  </code></pre>
