Change the menu font size

Hi and good job creating this awesome component
My question is ... can u please point me to how to change the categories menu module font size?
Im using the latest versions of your component and my theme is Balance from yootheme.
As you can see in the picture its prety big (13.5) and i would like to make it smaller..
thnx

found it by my self... i changed the file

templates\yoo_balance\warp\css\base.css

and

templates\yoo_balance\css\base.css

And i ask again mybe there is a module suffix that i can use so the change would apply only to the module?
thnx again

You can set a CSS suffix in the joomla options of that module. The, suffix to use will depend on your template. So you might want to ask your template provider.

Ok thanx for the answer i just thought there was something standard that i could use, anyhow ill go ask there too. Thanks again
