[SOLVED] Center all widgets in Right Sidebar

Hi I am working on a new site design where it would look better if all widgets appearing in the right sidebar were centered. There will be a mix of types, image, text translate, etc. Some widgets provide a placing option but some don't.

Is there a way to control the position of all widgets via a CSS insert?

Using WP 3.3.2 And Atahualpa 3.6.7 by the way.

Thanks
