Classic UI - Theme (Black)

hi, i would love to change the classic ui from white to black style. Would not want to switch to habpanel or basic ui, as i have seen for basic ui there is some customization “hacking” possible via CSS.

IS there something similar possible with classic UI, could not find anything discussed already. Thanks a lot Norbert

Yes there is a way with CSS too.
I can’t find it right now, I’ll keep looking
