Animate height of dynamic div
<p>I'd like to make the height of a div animate depending on the dynamic ad that is served inside.</p>

<pre><code>&lt;div&gt;
    // Dynamic Content
&lt;/div&gt;
</code></pre>

<p>The div has a minimum height of 90px, however if the ad served into the div has a height of 300px, I want the div to animate (css3 transition preferably) to the new height of 300px.</p>

<p>Is this possible?</p>

<p>At the moment the div just jumps to the new height, and the main content of the page jumps down with it. I'd just like this to be a smooth transition.</p>
