Looking for an effective method to implement CSS styling within a list cell in JavaFX?

As a beginner in JavaFX with limited knowledge of CSS, I struggled to conduct proper research and provide relevant information here. I apologize for any confusion or duplication. I am seeking a solution to apply CSS to JavaFX controls, specifically in a ListView as shown in the image below:

The issue I am facing is the inability to highlight the last item in the list (9x17 - Mother's Little Helper) by making it bold.

I welcome any suggestions on the most effective way to achieve this, whether through CSS or alternative methods. I am open to any solution that allows me to format the last item in the list. Thank you.

To emphasize the last item in a list, you can follow this method:

listView.getItems().get(list.size()-1).setStyle("-fx-font-weight: bold");

However, please note that this approach does not automatically update the list when new items are added in the future.
Here is an example of a list view that can be updated dynamically:

public class Main extends Application {

    private ObservableList<Label> list;

    @Override
    public void start(Stage primaryStage) {
        try {
            AnchorPane root = new AnchorPane();
            Scene scene = new Scene(root,400,400);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();

            ListView<Label> l = new ListView<>();

            root.getChildren().add(l);

            list = l.getItems();
            list.addListener(new ListChangeListener<Label>() {

                @Override
                public void onChanged(
                        javafx.collections.ListChangeListener.Change<? extends Label> c) {
                    for(Label l : list){
                        l.setStyle("-fx-font-weight: normal");
                    }
                    list.get(list.size()-1).setStyle("-fx-font-weight: bold");
                }
            });

            l.getItems().add(new Label("test"));
            l.getItems().add(new Label("test"));

        } catch(Exception e) {
            e.printStackTrace();
        }
    }

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

I understand that iterating over a list may not be the most elegant solution, but it is efficient in this case. If you prefer, you could create an update method to handle style changes only when necessary, such as after adding a batch of items.

Cheers,
Laurenz
