You could force the navigation to drop down at a specific width like this:
@media (max-width: 920px) {
.inside-header {
flex-direction: column;
}
.main-navigation:not(#mobile-header) .site-logo {
position: relative;
left: unset;
transform: unset;
display: block;
}
.main-navigation .menu-item-separator {
display: none;
}
.main-navigation:not(.slideout-navigation):not(.mobile-header-navigation) .main-nav > ul {
justify-content: center;
}
}
Let me know if that helps or not 🙂
