I'm trying to get rounded corners at te bottom of my headline box. I tried

-moz-border-radius: 5px;
-khtml-border-radius: 5px;
-webkit-border-radius: 5px;
border-radius: 5px;

but then I get four rounded corners, but I only want the corners at the bottom rounded. How can I manage this, can anybody help me? Thanks!

(The same for the top of the widget titles)

if you only specify one value, it applies to all four corners of a box. For a good explanation see http://blog.nixternal.com/2009.06.19/css-border-radius/

Thanks That works perfect for me!
