I'd like to add a span tag to display categories.
How it is right now:
<li class="cat-item cat-item-7"><a href="#">category #1</a></li>
How I'd like it to be:
<li class="cat-item cat-item-7"><a href="#"><span>category #1</span></a></li>
Unlike the other threads I've read, I'd like to do this inside my function.php file through a filter.
