wp_list_categories question…

I’ve been working on listing my categories via unordered lists. I’ve done the general look where each

• has a solid bottom border. Now, I’ve removed the Category title but it still styles the outer list.

So when I check my Category nav, there’s an extra border line that begins at the top of the category listing where the category title would normally be.

I’ve done the basic ‘title_li=’ to make it an empty string. It might be a bit confusing to understand but I’m hoping someone can help me with this. I’m currently working locally but I will make it live soon so you guys can see the problem directly.

Thanks in advance.
