There is. For the subject I think on your current layout it is under 'h3.entry-header' so if you search that on your CSS you'll find the coding for it. On the layout you're currently using I don't think it's actually seen on your layout. Unfortunately with S2 each layout tends to use different names for each part so usually you just have to poke and fiddle until you find the right bit. What are you trying to do? I might be able to help.
