thanks

ok
Is there any tutorial showing the correct details to put in the php header and how to correctly place the line in the div container / CSS. to get this jquery corner to work ?

I m failry new to CSS and i'm doing something wrong.

i know helping new ppl is a pain in the butt......im searching around
tanx

ok i got this sorted out using jquery

<script src="<?php echo $this->getThemePath(); ?>/jquery-corners-0.3/jquery.corners.js" type="text/javascript"></script>
<script>$(document).ready( function(){
$('.sidebar').corners("40px");
});</script>

everything in .sidebar would be nice and rounded

the jquery has to be in a separate folder..
