Okay, it looks like you have an idea of how to style portable infoboxes. My guess is you'd have to add a class to the element you want and then define it with.

However, I'm not really good with styling portable infoboxes, so I recommend you re-post your question at: Help, Questions and Answers board on the Portability wiki. If you aren't getting any help there right away, leave a message on my wall and I'll poke someone or leave a message on FishTank's wall with a link to your question.
