If what you want is to be able to test CSS changes on the fly on a running
javafx application during development for example; then you can also have a
look at CSSFX (https://github.com/McFoggy/cssfx).
If you do not want to setup CSSFX on your own, it has been integrated
inside Jonathan Giles "Scenic View" tool (
http://fxexperience.com/scenic-view/).
If you use a standard layout for your sources then the magic should apply;
if not you still can integrate CSSFX yourself to give it the good path to
your sources.
