jQuery, adding and removing a class on click
<p>Here's my code so far:</p>

<pre><code>$('.faq dd').hide();
$('.faq dt').click(function(){
    $(this).next().slideToggle('normal');
});
</code></pre>

<p>I would like the DT to include an "active" class whenever someone clicks on it and then an "inactive" class whenever someone clicks on it again. </p>

<p>How is that possible?</p>
