Here's the problem:
I tired to make the textarea from javafx have a black color, so i tried to add the parameter:
"-fx-background-color" with the value "black"
It did change something: Around the text area a black border appeared. I tried to change the background size with:
"-fx-background-insets" with the value "100" (for testing purposes, i know there are up to 4 values)
But nothing visual happend.
However, if i set the value to "-100", the screen 100 pixels outwards of the textarea is painted black. So, in theory, reversed parameter delivers the reversed result of what i want.
Therefore i ask: Why is it not working? I looked up other solutions, and they do it with the "-fx-background-color" parameter, so what a i missing here?
