+### Updating attributes of external recourses
+
+The {{cssxref("link-parameters")}} CSS property and {{cssxref("param")}} CSS function are now supported. This allows the user to update attributes of external resources, such as SVGs, that have their attributes set with the {{cssxref("env")}} CSS function. This means that single external resource can be used rather than creating multiple variations that only have different colors or other values. ([Firefox bug 2046153](https://bugzil.la/2046153)).
