Hi there,
Try updating this CSS you’ve added
.main-navigation .site-logo.navigation-logo img {
height: 120px;
}
to this:
.main-navigation .site-logo.navigation-logo img {
height: 120px;
z-index: 1;
}
For hover effect, can you give this CSS a shot:
@media (min-width: 769px) {
.main-navigation .menu > .page_item > a::after {
content: "";
position: absolute;
right: 0;
left: 50%;
bottom: 15px;
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
display: block;
width: 0;
height: 2px;
background-color: currentColor;
transition: 0.3s width ease;
}
.main-navigation .menu > .page_item.current-menu-item > a::after,
.main-navigation .menu > .page_item > a:hover::after {
width: 50%;
}
}
