I have added the code to change the width at which the Desktop Menu changes to mobile however the button is not responding and opening the mobile menu until 979 px is the width.
@media (max-width: 1140px) {
.x-nav-wrap.desktop {
display: none;
}
.masthead-inline .x-btn-navbar {
display: block;
float: right;
}
.x-navbar .x-nav-wrap.mobile {
display:block;
}
.x-navbar .x-nav-wrap.mobile.collapse {
display:none;
}
.x-navbar .x-nav-wrap.mobile.collapse.in {
display:block;
}
}
