Declaring Variable In JavaFX CSS File

Question

I've been inspecting the "caspian.css" distributed by Oracle in the JavaFX runtime library, and I see they have declared some color values as variables. Eg: ``` -fx-base: #d0d0d0; // Caspian.css, Line 47 ``` ...and then they used it as value of some other property, like: ``` -fx-color: -fx-base; // Caspian.css, Line 96 ``` Now, what I want to do is to declare a measurement unit (`-fx-radius-default: 10px`) and then use it everytime I need to set radius of a control, for instance: ``` -fx-border-radius: -fx-radius-default; -fx-background-radius: -fx-radius-default; ``` I have been unsuccessful so far. My question is: Is this possible, at all? Edit: Adding experiment details Details Here is my Experiment.fxml file that I created on JavaFX Scene Builder 1.1: ```

Accepted Answer

Unfortunately it seems to work only for colors. But you need to ensure that your variable is "visible" from rule which uses it:

```
* {
   -fx-base2: #e00;
}
.track {-fx-background-color: -fx-base2;}
```
