为 BorderPane 设置背景颜色在行中有效，但不在 CSS 文件中

Question

So I have a border pane and I want to set it's background color with -fx-background-color: black . When I do this 'inline' like this:

    borderPane.setStyle("-fx-background-color: black");

it works fine, but if I instead add a class selector to it and try setting the color within the selector, like this:

    borderPane.getStyleClass().add("env-pane");

and css like this:

.env-pane {
  -fx-background-color: black;
}

No changes take place. I'm not sure if this is related. Looking at the Javafx css reference the pane class has the -fx-background-color property.

If it helps, I added the style sheets to the scene and other components change based off of it fine.

I tried to re-create your problem but seems like it works for me. I'm using JDK 8 by the way.
