Hi,
This issue happens because the menu items and the menu bar items are 2 completely different sets and the border is only applied to the primary menu.
That said, try this CSS:
@media(min-width:769px){
.inside-navigation.grid-container {
border-top: 2px solid #eee;
border-bottom: 2px solid #eee;
max-width: 1280px;
width: fit-content;
padding: 0 0 !important;
}
}
@media(max-width:768px){
.inside-navigation.grid-container {
width: 100%;
}
}
