<div class="wrapper">
<div class="dt"><img src="/news_pics/16.jpg" alt="pic 4" width="100px" height="75px"/></div>
<div class="dd"><p>8 05 2012</p><h4><a href="#">News 4 title</a></h4></div>
</div>
EDIT:
The <div class="wrapper"
helps to clear the float
and display the elements properly in all browsers including IE6 & 7.
