Rounded corners in footer boxes


New member
I almost finished coding my new skin, have some extra footer block, and two boxes in it. I would like them to have rounded corners like some xenforo elements. Anyone knows how to do this?

Footer looks like this: (login/password: test/test)

And should look like this:

I know it's more css then xenforo question, but I'm curious how it's done in Xenforo (I see it in breadcrumbs, and navigation menu ...)
