我知道可以使用StyleableObjectProperty覆盖为节点定义的动态css属性。我现在问如何更改＆＃34; .root＆＃34;中声明的root属性？ css样式表中的类，所以所有节点都将继承此更改。
我想举例来说，更改用于我的应用程序中所有文本的字体颜色属性。此颜色可以在应用程序中动态更改，并应适用于使用它的所有节点。

一般来说，找出CSS设置的最佳选择是查看默认样式表的source code。
例如，字体颜色实际上是通过自动选择三种固定字体颜色之一来管理的，具体取决于背景的强度（例如，您不会在白色背景上以白色文字结束） ：
/* One of these colors will be chosen based upon a ladder calculation
* that uses the brightness of a background color. Instead of using these
* colors directly as -fx-text-fill values, the sections in this file should
* use a derived color to match the background in use. See also:
*
* -fx-text-base-color for text on top of -fx-base, -fx-color, and -fx-body-color
* -fx-text-background-color for text on top of -fx-background
* -fx-text-inner-color for text on top of -fx-control-inner-color
* -fx-selection-bar-text for text on top of -fx-selection-bar
*/
-fx-dark-text-color: black;
-fx-mid-text-color: #333;
-fx-light-text-color: white;
所以你可以用
之类的东西来覆盖它们.root {
-fx-dark-text-color: navy;
-fx-mid-text-color: blue;
-fx-light-text-color: lightskyblue;
}
在外部样式表中，它将更改整个应用程序的字体颜色。 （如果您确定您的背景永远不会成为问题，您可以将它们制作成相同的颜色，但我不建议这样做。）
此处设置的属性实际上是＆＃34;查找颜色＆＃34;。由于查找颜色的值是从父节点继承的，因此这些值将应用于整个场景图。
如果您想从代码中执行此操作，则可以使用
实现相同目的root.setStyle(
"-fx-dark-text-color: navy ;"+
"-fx-mid-text-color: blue ;"+
"-fx-light-text-color: lightskyblue ;");
