AB Accordian Styling

I’m seeing reports of people mentioning styling their AB Accordian blocks.

However, the only option I see is the size of the font.

I’d love to be able to adjust the color, in particular of the accordian block.

I want to use the accordian on the home page, but the big, boxy gray squares are really dominating the page… to the point that I don’t want to use these blocks if I can’t make them white.

I’ve been trying some CSS from my coding book, but I can’t get anything to work.

Can anybody help me out here?

Thanks!
