Font settings for category sidebox?

I'm sure there's an easy fix for this, and I'm just not finding it.

In my category sidebox, I'd like the subcategories to be in a smaller font size than the categories (so when the categories are expanded, the subcategories display in a smaller font).

I'd also like to both categories and sub-categories bolded.

Can anyone tell me where I can control these settings?

Thanks!

Locate the stylesheet.css for your active template and edit it. Find or add the following: adjust font sizes and colors to your liking

.category-subs-parent {
color: #006633;
font-size: 1.4em;
}

a.category-products {
color: #9a9a9a;
font-size: 1.2em;
}

Thanks Kobra.
The template I'm using didn't have a section for those settings in it, which is why I was lost!
I added them, and all is well. thanks for your help.
