check to see if first element is <h3>, if so addClass. if not, do nothing
<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>
