问题
Is there any way to see the applied CSS-Rules for JavaFX-Elements? Or there is a published reference with the default CSS-Rules available?
I would like, for example , to know the color of Toolbar's border.
回答1:
The CSS file is located in javafxrt.jar at jfxrt.jar!/com/sun/javafx/scene/control/skin/caspian/caspian.css .
Unfortunately, there is no API access to the CSS styles of an element as of now, though that is apparently being discussed for JavaFX 2.2.

Here is the extracted caspian.css on pastebin - http://pastebin.com/0PebD9nR

With JavaFX 8 the default CSS is a new theme called Modena.
The modena.css for the build version Java8_91 can be found here:
https://gist.github.com/maxd/63691840fc372f22f470
If you search the css file in different JDK versions this is the way to go.
JDK below 10.0: $JAVA_HOME/jre/lib/ext/jfxrt.jar --> com/sun/javafx/scene/control/skin/modena.
JDK for 10.0 and higher: $JAVA_HOME/jmods/javafx.controls.jmod --> classes/com/sun/javafx/scene/control/skin/modena.

From Skinning JavaFX Applications with CSS: Default Style Sheet,
The default style sheet for JavaFX applications is caspian.css, which is found in the JavaFX runtime JAR file, jfxrt.jar
and
Use the following command to extract the style sheet from the JAR file:
jar -xf jfxrt.jar com/sun/javafx/scene/control/skin/caspian/caspian.css
and then just use a css viewer.

As for the end of 2019 the default modena.css can be looked at official jfx github repo:
https://github.com/openjdk/jfx/tree/master/modules/javafx.controls/src/main/resources/com/sun/javafx/scene/control/skin/modena
Or you can look inside Maven javafx-controls. For example in javafx-controls-13-win.jar go to /com/sun/javafx/scene/control/skin/modena/
