I am using JavaFx to create a front-end to the cli application called spicetify. I am not using an fxml file for the layout instead I am using different classes for layout purposes.
One such class is the Sidebar class. In it I define how the sidebar should look and then create an object of it on the window/page that I need. Whenever I add buttons to the sidebar The colors of the window where the Sidebar object is created go blank/white.
I am unable to find anything by googling and hope that the information provided is enough.

Default Modena CSS has a gray background in panes.
When controls are loaded CSS will be applied to the entire scene, as controls use CSS.
Without any controls, CSS (for performance in straight rendering of graphics primitives) will only be applied to the scene if you specifically apply it.
For more information, and steps you can take to remove the default color from pane backgrounds, see the related question:
