Centering images in category view

[AndeeM]

Hi!

I'm looking to center the images in the category view.

Such as, I click on a category listing(E.G. Mens Wear) and it shows a list of images of the sub categories that seem to be aligned left, which if theres a odd number of sub categories it leaves a ton of white space on the right hand side.

Example of what I mean- www dot outdoorgear dot net/mens-clothing-c-67.html

My question: Is there any way to have the sub category images centered so when there is an odd number of sub-categories it will distribute the space evenly on both sides.

What I tried:

In css, changing the .categoryListBoxContents div rule to margin-left auto, margin-right auto, does nothing.
I found it working slightly when I do a padding or margin-left: 50px; and a padding or margin-right: 50px; but it still seems to mess it up quite a bit.

Can anyone help? Still running into the same issue
