The Divi Theme has a neat little menu button which appears on small-screened devices (mobiles, etc). If you find yourself wishing that you could have the menu button on all screen sizes (and get hide the menu links), here’s how to do it – just add the following CSS to Divi:
@media only screen and ( min-width:980px ) {
#et_mobile_nav_menu { display:block !important; margin-bottom:20px; margin-top:6px }
#top-menu-nav { display:none; }
.et-fixed-header #et_mobile_nav_menu { margin-bottom:0; }
}
