I got it with…
Its normal that the custom.css is already empty.
The MM has his own css… Called Main.css.
Every Module has is own css too. For example its Called Modulename.css.
When You want to change something(customise it) , You can write it in your custom.css.
Today I did some work on my mirror again.
I installed two modules and configured them.
With one I made the mistake of using “npm install” in the “Magic Mirror” folder.
However, everything went normally for the time being.
After further settings in the config and another restart, the screen remained black with a cursor in the upper corner.
I hope you can help me and all my work has not been in vain.
