Is it possible to make this box's corner round with same html tags. without using any other tag and border-radius property and javascript. but i can use css classes and background images. and box height should be depend on content of <p>grr</p>

Width of Box and height of <h2> is fixed , but I need height of content flexible.

<h2>Nulla Facilisi</h2>
<p>
   Phasellus at turpis lacus. Nulla hendrerit lobortis nibh. 
   In lectus erat, blandit non feugiat vel, accumsan ac dolor. 
   Etiam et ligula vel tortor tempus vehicula porttitor ut ligula. 
   Mauris felis odio, fermentum vel
</p>

Edit : What is the best possible way to achieve this without css border-radius property which is not supported by internet explorer?
