Editing Widget Styles

Hi All

I have been supplied with a template from a client and im finding it really hard to locate the code to style my custom widgets. The template was supplied with a 3 coloumn layout and i had to create 4 footer widgets. Im no stranger to wordpress or the code, but this is proving very difficult. I was wondering if someone could look at my source and help me to identify where i might be able to change the sytle.
