Bold Category In Menu

Hello,

Does anyone know how I can make 2 of my categories bold in the menu?

I have tried messing around with the "User-defined CSS-class" and adding in CSS but I can't get it working. I must be missing something simple?

I am using the AlexBranding Unitheme v1

Try to make a post here
