i changed the font for the navigation links to the custom font I wanted but when the nav links go into a side bar on the mobile version, the font is still the old one i do not want. How do i change the font of the side bar to the custom font i want?

Add to Home > Design > Custom CSS

#sidecarNav nav * {
    font-family: fantasy !important;
}
