How can i load css ?

Answer 1

You need an URL and call toExternalForm in order to load a css file into your project.
Use the ClassLoader for that:

scene.getStylesheets().add(getClass().getResource("/style.css").toExternalForm());

Answer 2

For those who can't find css the way from accepted answer use classLoader:

getClass().getClassLoader().getResource("css/style.css").toExternalForm()

If you use maven it will find your css under resources/css/ dir.

Answer 3

In my case ,I want to load a css file from disk and I do it as this article said and it worked for me. code snippet as follow:

scene.getStylesheets().add("file:///E:/csse2002-7023/src/csse2002/block/world/main.css") 

Answer 4

Simply add package name with .css file.

Your code will look like this:

scene.getStylesheets().add("sample/appCssFile.css");
