To reproduce run following code

import javafx.application.Application;
import javafx.builders.SliderBuilder;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class SliderTest extends Application {

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

    private Parent getContent() {
        VBox list = new VBox(10);
        list.getChildren().add(SliderBuilder.create().min(0).max(100).value(25)
                .style(
// "-fx-minor-tick-count: 5;" +
                 "-fx-major-tick-unit: 50;"
                + "-fx-show-tick-marks: true;").build());
        return list;
    }

    public void start(Stage stage) {
        stage.setX(100);
        stage.setY(100);
        Scene scene = new Scene(getContent());
        stage.setScene(scene);
        stage.setVisible(true);
    }
}
