[jQuery] jQuery Tabs Issue in Internet Explorer


If this is a duplicate post, I apologize.

I'm working with jQuery tabs found here: http://www.stilbuero.de/
As you can see in IE, it is not displaying properly. I believe this
is CSS related, but don't know enough to be able to fix it.
If you view it in Firefox, it works just as I want. Can anyone help
me in troubleshooting this issue?
I appreciate the help.
