If you copy paste this into the custom css box and save it should give you a bit more room on your topmenu:
.topmenu_element {
background-image:none!important;
padding-right:0px!important;
padding-left:0px!important;
height:56px!important;
line-height:56px!important;
margin-top:6px!important;
transition:.3s
}
.topmenu_element:hover {
background-image:none!important;
background:rgba(255,255,255,0.1);
padding-right:0px!important;
padding-left:0px!important;
height:56px!important;
line-height:56px!important;
margin-top:6px!important
}
.topmenu_submenu {
top:70px!important
}
you could also add this if you want the seperator even smaller:
.menu_sep {
background-image:none;
background:rgba(255, 255, 255, 0.35);
width:1px;
margin-top:7px;
height:55px!important;
}
