<p>Gradually change the transform-origin from "50% 50% 0" to "0 0 0", and back:<p>
<p><b>Note: </b>The grey DIV element indicates where the DIV2 element would be without the transformation.</p>
<div id="DIV1">DIV1
<div id="DIV2original">DIV2</div> <div id="DIV2">DIV2</div>
</div>
<p>The transform-origin property is <em>animatable</em> in CSS.</p>
