Setting just the width and float css properties would get a wrapping panel. The folowing example work just fine:
<div style="float:left; width: 250px">
Pellentesque feugiat tempor elit. Ut mollis lacinia quam.
Sed pharetra, augue aliquam ornare vestibulum, metus massa
laoreet tellus, eget iaculis lacus ipsum et diam.
</div>
Maybe there are other styles in place that modify the appearance?
