Product page border/box?

[nickb]

When you click on a product and view the product, it comes up in the center of the page with no border or box. How can I but it in a box or border?

 

Thanks for any help.

 

 

Here is a pic of my page without a border.

 

 

Here is another pic with a drawn on border showing you what I would like to do.
