Credits go to @kmh for creating this style. It comes in both a light and dark version (check the links for usage instructions).
If you don’t want to fiddle with code and stuff, loma.ml has already installed it server-wide, and should be available straight away for new accounts (If not, go to Settings>Display>General Theme Settings and change it from there. Or follow the guide in any of the links above).
@Zero22xx There are multiple Friendica instances. You can check them in the Friendica Directory (in the servers section) or other more global lists of Fediverse servers like the-federation.info, FediDB etc. Friendica has groups too, but besides the [email protected] (or probably even the [email protected] one) they’re pretty much lacking activity (you’re still free to post anyway, there are plenty of them).
If you need some help, you can also post on the former one by creating a regular post and mentioning the group with “!” or “@”. I have also created a megathread with various resources and a small Q&A (it’s actually vice-versa tbh, since the Q&A took the most space on it, but I digress) in order to get yourself started: https://libranet.de/display/0b6b25a8-2167-82af-600d-9ea129892452
