    Not sure how to help you but your script may solve my problem.
    Could you please share where rootElements came about.
    I am trying to replace the color in the background property of the USS

    Thanks

    Yes, the Q call will find the element with a specific name, and does not use that pattern. However, if you have an element with a unique name (in your case "Content"), you can find it directly from rootElement because it will recursively find for it - i.e. you don't need to be holding a reference to the immediate parent to get it. So in your example, calling 
    rootElement.Q("Content")
    will return you the correct Visual Element.

    Code (CSharp):
    1. document.rootVisualElement;
    document is the reference of some UIDocument .
