1. Cascading Style Sheets (CSS) help style web pages and let designers give a uniform look and feel throughout an application, widget, or entire web site. You can use CSS to similarly style JavaFX nodes. (See “Cascading Style Sheets (CSS)” for details on applying styles to JavaFX nodes.)
2. Java developers may wonder where function main() is. As it turns out, the JavaFX compiler generates a main() for you, but from a developer’s view, you have just a script file.
3. Well, almost. If you don’t define function create, then you must declare the class abstract. The Piano example (see “Project Piano”) uses an abstract class.
