Been working on my cart for a few days now. A little confusing at first, but I am beginning to grasp the where's and how to make changes. I have searched and searched but haven't found an answer to this question. I even did a google to see how to add a HR to my CSS, but when I add what I believe is the right code, my left categories sidebox lengthens considerably. I am brand new to CSS, so I am sure I added the wrong code. I have since ditched the code I added.

My goal is to add a horizontal line below the EZ pages links. I think it would look better to have a little separation between the EZ pages and the main content.

Here is my current page: http://mistkits.com/cart

Can someone give me a push in the right direction?

I am also open to other suggestions.
