@maphorn site url? Basically you add the changes in your own theme’s style.css file. Do not make changes in /bp-themes/bp-default/_inc/default.css because those changes will be overwritten when you upgrade BuddyPress.

@maphorn You will lose those changes each time you perform a BP update, creating a child theme to hold style adjustments is the recommended approach.
