External Data Provider Help, Please

On an html page, I'm attempting to display Latest Forum Posts.

The feed is not formatted correctly. Therefore, I need to create a stylesheet (apparently), and I don't have a clue on how to do it.

The feed is coming through as white text; no spacing b/t posts; no bullet separating the posts.

Question:

**How do I create a stylesheet to format this feed, if that's what's needed?

Thank you,
Mike
