views theme list

Hi All

I'm having trouble changing the look/theme of a view I have created. I think it may have something to do with the original theme. Is it possible to change the look of the view?

You can view how my views appear here:

I really wish to take off the borders at the top and bottom and want to have rounded corners. Is there any way i can do this guys?

Thanks in advance, you guys rock! :)
