Animate or scale from center
<p>Any ideas on how to animate the width and height of a div from the top center?
Tried using effect('scale') but this is based on a show/hide so snaps back after completion.</p>

<p>Then tried a normal animate:</p>

<pre><code>$('.box').animate({'width':200px,'height':200px,margin-left:-100px});
</code></pre>

<p>This works, but as there is a line of .box, I want the others to react and push to one side.</p>
