Reply To: Home/Main slider height changes

eVision support sent me this CSS snippet. Works well for me.

Please update this code in Additional CSS of customizer.

.cycle-slideshow .slide-item {
   height: 400px !important;
}
@media (min-width: 768px) {
   .cycle-slideshow .slide-item {
       height: 500px !important;
   }
}

Hope this helps your queries.
