If you are creating a Javafx / B4j project with multiple themes & stylesheets, then you need this. You can create your own Pseudo classes for use in the stylesheets. Sorry, this one is definitely not cross platform.
I thought it was going to be cumbersome, but it came down to 5 lines of code.
It is simple to use:
And in the stylesheet:
The example project shows it's use with a Button, Label and B4xPlusMinus view. There is also a B4xLib with all 5 lines of code.
There are no external dependencies.
Enjoy.

It is simple to use:
B4X:
' Declare a global variable for the pseudo class
Private AltColorPseudoClass As PseudoClass
.
.
.
'Initialize the class in AppStart with the name of the PseudoClass
AltColorPseudoClass.Initialize("altcolor")
'Then find an appopriate place to update it
Private Sub Label1_MouseEntered (EventData As MouseEvent)
AltColorPseudoClass.SetState(Label1,True)
End Sub
Private Sub label1_MouseExited (EventData As MouseEvent)
AltColorPseudoClass.SetState(Label1,False)
End SubAnd in the stylesheet:
B4X:
.label:altcolor{
-fx-background-color:Blue;
