Main categories horizontal, subcategories vertical

Hey...

One of my last questions after finishing the entire lay-out for my hikashop.

I want to put the main categories centered and next to eachother, while the subcategories should be positioned centered, beneath eachother. Is this possible with the CSS file?

I think it is, because when you go to checkout without having any products in your cart, you get the categories lined up horizontally, but when you go to the webshop, they are lined vertically.

thanks once again!

This is the horizontal version. The one you will see when you click on checkout with nothing in the cart. I'd like the main category to be the same!

Next post will be the vertical version, which I do not want it to be!

However, I'd like the horizontal one to be centered, now it is positioned to the left!

Thanks guys!

Lol, and to think that I've been actually searching for hours (even in that menu)...

thanks!!!
