Is it correct that I can't use  for certain infobox types or themes alone and only can set it globally?

The change I tried to implement isn't shown, and the MW shows the note "Don't use adjoining classes." when I have .portable-infobox.type-product .pi-title { font-size: 120%; } in it, whether with or without space between those two.
