[Augusto Sacchetto]

Hi,

I would like to assign a diferent CSS style to each product listed on 
products list so each get a different color background, so for example, one 
product get a white background and the next a grey background, and the next 
a white background. I hope you understand what I mean...

If someone can give me a hand with this I would be gratefull,

Thanks for your time,
