I want to add a dark gray outline for each product. 

No, I have 8 products listed on the product page, they  are all next to each other with a white backround. What I would like to do is to separate the products in individual squares or outline so it looks cleaner. 

I creating a multi product store but Im having issues with the layout.I would like to separate each product with a dark square outline.I would also like the squares to be the same sizes.

how do I seperate the products on my product page into seperate shaded squares
