XF 1.5 How to change the post background for the users of one group?

[Evgeniy Grygorovych]

Good day. We want to make a "bluepost"-like theme for our forum. We want to make a custom background color for our moderators and administration posts. Is this somehow possible with the default xenForo 1.5 tools or not?
Thank you.

You can use the staff class in XF1 to style messages.

Where can I find some more info about that?
