How do I add a class to a default bootstrap class
<p>Im want to give the panel-heading class an identifier so i can target it in my css without changing any of the other panel-heading's, how do i go about this?  </p>

<pre><code>&lt;div class="panel panel-default"&gt;
    &lt;div class="panel-heading"&gt;&lt;h2 class="login"&gt;Welcome Back!&lt;/h2&gt;
    &lt;/div&gt;`
</code></pre>
