try this: create a Java file

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class HelloStyledWorld extends Application {

    @Override
    public void start(Stage primaryStage) {
        Button btn = new Button();
        btn.setText("Say 'Hello Styled World'");
        btn.setOnAction(new EventHandler() {

            @Override
            public void handle(ActionEvent event) {
                System.out.println("Hello Styled World!");
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(btn);

        Scene scene = new Scene(root, 300, 250);
        scene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());

        primaryStage.setTitle("Hello Styled World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

put the style.class in the same package as the .java file (or in the corresponding resource folder if you are using one.

verify that the build includes the correct css file into output folder. you can

System.out.println(getClass().getResource("style.css").toExternalForm());

to console to see where JavaFX is searching for the css and check if the css is available there.
