OK, so I looked deeper, and I found the following.
If I check rounded corner on menu bar and Sub menu, the theme generates the rule
@media (min-width:768px) {
.menu-primary ul.sub-menu, .menu-primary ul.children{
-moz-border-radius:8px;
-webkit-border-radius:8px;
border-radius:8px;
z-index:2001;
padding-top:6px;
padding-bottom:6px;
background-color:#FFEEBB;
}
.menu-primary ul.mega-menu li{
-moz-border-radius:8px;
-webkit-border-radius:8px;
border-radius:8px;
z-index:2001;
}
}
Which is exactly the same as Morris rule except it has the proper Z-index.
So @weaver, it does seem his rule with the z-index-90 comes from the theme, I just don’t understand why I don’t have the same value as him (unless it was fixed in the beta version I am using)
To get the rule, you just need to check rounded corners for both menus and sub menus.
@Morris, Your rule should be just fine to override for now
There is no documentation on the Z-index changes
