Modyfying product listing and new products listing

[pavlo]

Hi,

I am very new to use php and oscommerce. I want to modify the image looks and table background of product listing on every page. When i change the color from infobox classes in stylesheet.css then the color of left column, right column and middle product table all are changed at same time but i want to modify only "product listing table" and "new products for the month table". How can I achieve this without modifying left and right column.

Thank you.
