I believe it has something to do with this CSS, which I used to put a border around the submenu drop down box. When I change the “border:1px” to “3px”, the border AND the green line get thicker. Not sure why the green line is showing though. I appreciate your help!
@media (min-width: 769px) {
nav .main-nav .mega-menu {
position: static;
}
.main-navigation .sub-menu {
border: 1px solid #16a286
}
.main-navigation .sub-menu > li:not(:last-child) > a {
border-bottom: 1px solid #d7d8d9;
}
.main-navigation .sub-menu > li > a {
margin-left: 10px;
margin-right: 10px;
}
