scene.getStylesheets().add("/mystyle.css");
The mystyle.css file has to be placed in the src/main/resources folder. Let’s do it, and add the mystyle.css file with the following content to the HelloWorld example:
#text-hello {
:fx-font-size: 20px;
-fx-font-family: "Arial";

-fx-text-fill: white;
-fx-background-color: slateblue;
}
