Css Scrollen van div's

Hallo allemaal,

ik heb een website gemaakt opgebouwd uit div's.

visit: http://www.bernardveeningen.nl/Def1/Index.html

Zoals je ziet is aan de linker kant de div News niet even lang als content. Ik heb echt geen idee hoe ik deze even lang krijg als mijn content met css. WEet iemand dit?

Mijn Css code:

<?php
@charset "utf-8";
/* Lavidas CSS */

* { margin: 0px; padding: 0px; }

body {
margin: 0px;
background-color: #ffffff;
font-family: Arial, Helvetica, sans-serif;
background-image: url(../images/OptionBar.gif);
background-repeat: repeat-x;
}


h1 {
font-weight: bold;
font-size: 12px;
}

p {
font-weight: normal;
font-size: 10px;
}
