Editing the FAQ look in CSS

Hello, I am very raw when it comes to editing CSS. I know enough to know that I only edit when I have very detailed instructions about what and where to change. I’m trying to figure out how to change the color and size of my FAQ questions while using the jquery collapse/expand option. I’m not happy with how the H options look.
