how to add and remove a class in jquery every 4 seconds
<p>for some reason, this isn't adding and removing a new class on elements with the class of post, every 4 seconds. jquery loads correctly, as does this. chrome shows no errors with the code.</p>

<pre><code>$(document).ready(function(){
    $('.post').addClass('display').delay(4000).removeClass('display');
});
</code></pre>
