Is this possible - widget question

Is it possible to make the widget be centered within the space it is allotted instead of being left justified? I've tried all sorts of things with the html/tags/code/whatnot but none of them are working in the confines of the blogger gadget. Short of accepting it off kilter from everything else or using the gadget in "fill the space" mode which makes it way too big .. is there anything that can be done?

I would like to fix the same problem - it seems a border around the entire group, rather than all book covers being pushed up to the top left corner of the widget window would be helpful - any solutions?
