CSS: Underlining Links in Categories Sidebox

Hey guys-
I have another one I'm completely stumped on.

site- h c g s u p p l y . c o m / s t o r e

I want the links in the sideboxes (on the left side only) to be underlined the entire distance of the column. It's working on the other boxes (Information, Articles, etc). However, for some reason, it's not working on the Categories/Products box. I have this CSS which is working for the other boxes...

.sideBoxContent li {
margin-bottom: 5px;
border-bottom-width: 1px;
border-bottom-style: solid;
border-bottom-color: #dddddd;
}

Any ideas as to why that won't work on the Categories/Products side box?

Thanks a ton guys!

Try this and adjust to suit

#categoriesContent a:link {
  border-bottom-style: solid;
  border-bottom-color: #4f4f4f;
}

In the future please add only one space to break link as in

Thanks for the help-
That didn't work. I figured out that it's because the Categories are dynamically written into the page, and DOES NOT use UL or LI's to list them (not sure why that is). So my original code won't apply to it.

Your code only underlines the last link in the section. Additionally, it only underlines the actual text in the link- I want the entire width of the column underlined- like the ones in the Information and Articles boxes.

Is there a way to change this to a UL LI style for displaying the links?

ok- just installed a mod - the Category UL LI mod (or something similar). That worked great!
Thanks!
