Introduction to CSS Styling
Unlock Audio Lesson
Today we will discuss how to use CSS for styling in JavaFX applications. CSS allows us to visually enhance our components. Can anyone tell me what CSS stands for?
Cascading Style Sheets!
Exactly! CSS helps us define the look and feel of our UI. Why do you think it’s beneficial to separate styles from the application logic?
I think it makes the code cleaner and easier to manage.
Right! Keeping styles separate makes our applications easier to maintain and change over time. Let’s look at a simple CSS rule.

Now that we understand the syntax, how do we apply these styles in a JavaFX application? Can someone guess?
We probably need to load the CSS file in the Java code, right?
Correct! We load it using the Scene’s getStylesheets method. For example, `scene.getStylesheets().add(getClass().getResource('style.css').toExternalForm());`. Once that’s done, the styles will be applied. Let’s run through how this impacts our visuals.

CSS Styling in JavaFX
CSS (Cascading Style Sheets) in JavaFX is a powerful tool that allows developers to apply a variety of styles to their application’s UI components, making the interface more visually appealing. The ability to use CSS means that developers can separate the design from the application logic, adhering to the principles of clean code and architecture.
In this section, you’ll learn about:
- Basic syntax of CSS as applicable to JavaFX.
- How to define styles for various UI components like buttons, text fields, and more.
- The flexibility and power that CSS brings to user interface design.
For example, a simple CSS rule can define the background color and font size of a button:
This snippet illustrates how straightforward it is to change component appearances using CSS. The significance of CSS in JavaFX enhances the development process, allowing for rapid design iterations and easily maintainable styles.

.button {
-fx-background-color: #00ff00;
-fx-font-size: 14pt;
}
Detailed Explanation
This CSS code snippet specifies the styles for buttons in a JavaFX application. The first line sets the background color of the button to a bright green using the hexadecimal color code #00ff00. The second line sets the font size of any text on the button to 14 points (pt). This means that whenever a button in your JavaFX application is rendered, it will have a bright green background and the text displayed on it will be of size 14pt.
Examples & Analogies
Think of this styling like dressing up for a party. Just as you might choose a bright green outfit to stand out and make an impression, here the button is dressed up with a bright green background. The font size is like choosing how big or bold the text will be on a party invitation, ensuring it's easy for guests to read and catch their attention.
