Style Widgets Side by Side?

Ok so I know that you can style widgets side by side with atahualpa by making two columns and have done that before.

But right now what I have going on is a widget called the Tabber Widget.

Basically it creates tabs on the top of the screen. On the backend it creates widget areas for each of those tabs. So then I add widgets into those areas.

So unless I make a bunch more widget areas inside of that widget area the old way of using columns won't work.

Does that make sense? Eh. Regardless what I need to know is can I align widgets side by side just with CSS?

You can see it in action here:
