BuddyPress.org

I’ve been looking around in the css files.

In buddypress-home > css, I found custom-sample.css. The comment in the file says to rename it as custom.css and put style changes in that file.

This way style changes will be preserved even while updating the buddypress-home theme.

This is the answer I needed and I’m posting it in case it will help someone else too. Thanks, Andy, for enabling this through your file structure.
