Is there a listing of classes, IDs, divs for Marketpress products so I can modify the CSS.

I am buiding a website and incorporating Marketpress into the site.

The Classic theme layout forproducts is a start, but I need to change the CSS.

Do you have a listing of the div/classes/IDs applied to the product elements so I know what to change?

I did manage to get each item image and H3 centred but it was not an easy task!

i.e. I want to put a border around each store item and increase the spacing between rows, but I cannot find a containing high level div that each item is built into.

Please help,
