Need help with hover highlight color

edited September 2017 in Style Development Firefox
In firefox:
This is my panelui-menu-button on click/ hover. Is it possible to change this grey highlight/ hover color to something different like black, blue etc?


  • Well i found it & figured it out. It's:

    --toolbarbutton-hover-background: rgba(0,0,0, 0.15);
    --toolbarbutton-hover-bordercolor: rgba(0,0,0, 015);
    --toolbarbutton-hover-boxshadow: none;
