1. Style Multiple Buttons with Inline CSS

Write a JavaFX application with multiple buttons. Apply different styles to each button using inline styling and observe how various CSS properties impact their appearance.

Sample Solution:

JavaFx Code:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        // Set the title for the primary stage
        primaryStage.setTitle("Styled Buttons");

        // Create Button 1 with specified styles
        Button button1 = new Button("Button 1");
        button1.setStyle("-fx-font-size: 14; -fx-background-color: #FF6347; -fx-text-fill: white;");

        // Create Button 2 with specified styles
        Button button2 = new Button("Button 2");
        button2.setStyle("-fx-font-size: 16; -fx-background-color: #1E90FF; -fx-text-fill: white; -fx-border-color: black;");

        // Create Button 3 with specified styles
        Button button3 = new Button("Button 3");
        button3.setStyle("-fx-font-size: 18; -fx-background-color: #32CD32; -fx-text-fill: white; -fx-border-radius: 5;");

        // Create a VBox layout to hold the buttons with spacing
        VBox vbox = new VBox(10, button1, button2, button3);
        vbox.setSpacing(10);

        // Create a scene with the VBox layout
        Scene scene = new Scene(vbox, 300, 200);

        // Set the scene on the primary stage
        primaryStage.setScene(scene);

        // Display the primary stage
        primaryStage.show();
    }

    // Launch the application
    public static void main(String[] args) {
        launch(args);
    }
}

Explanation:

In the exercise above,

Button 1 has a red background, a smaller font size, and white text color.
Button 2 has a blue background, a larger font size, white text color, and a black border.
Button 3 has a green background, a larger font size, white text color, and rounded corners.

Run this JavaFX application to observe how different CSS properties applied using inline styling (setStyle) affect the buttons' appearance. Adjust the styles or properties as desired to see their impact on the button's appearance.
