bbPress.org

I have installed bbPress forums into my Genesis/Dynamik Website Builder parent/child theme and it works nicely. However I have some confusion on how to alter the CSS of the bbPress forums.

The general site settings have a black background with white font used. The white font is displaying on the bbPress forum pages, but not the black background.

This will be a question for those who are familiar with Genesis/Dynamik Website Builder.
I have put the following code into the Genesis/Dynamik Custom CSS field but it still displays with the default light background colors in bbPress posts.

#bbpress-forums div.odd, #bbpress-forums ul.odd {
background-color: #222222;
}

#bbpress-forums div.even, #bbpress-forums ul.even {
background-color: #444444;
}

Any assistance would be greatly appreciated.
Thanks,
Jason Davis
