Hi David – thanks. That works for the mobile dropdown menu (see live site), but not for the hamburger background. I think I’ve worked it out with this:
/* change background color on hamburger and menu dropdown on mobile */
.has-inline-mobile-toggle #site-navigation.toggled {
background-color: #fff;
}
.mobile-menu-control-wrapper .menu-toggle, .mobile-menu-control-wrapper .menu-toggle:hover, .mobile-menu-control-wrapper .menu-toggle:focus, .has-inline-mobile-toggle #site-navigation.toggled {
background-color: #fff;
}
Does that look right to you?
