Wrapper Div border problem

Hi guys, I’m hoping you can help me with a fairly newbie-style problem.

I’m trying to put together a custom WordPress template for my girlfriend’s jewellery business so that she can update it easily.

I’ve ran through a few tutorials and I think I’ve got the basics down. I’ve started to put together a mockup, and I’ve ran into a problem already – namely getting a thin border around the wrapper div I’ve created for the content. The background image is showing, but no border. You can see the original site at https://www.fuzionjewellery.com as an example of what I want to do.

I’ve uploaded a screenshot of how it looks just now – https://i7.photobucket.com/albums/y279/Tornik/Clipboard01.jpg

The code is as follows:
