Topic: How to use CSS to realign widgets in WP ?;

Hi,
I have been trying to figure out this for 5 hours now and my head hurts. lol. I have a wordpress theme and 3 widgets on the bottom. 2 of them line up perfect but not the third one. It needs to come down 10px from top and 12px from right side. I need the css to target just the one widget not all three. Can you tell me exactly what i need and where in the stylesheet to put it please?
