Hi Giuseppe DI STEFANO
Yes, it’s possible just you need to add below CSS code in Additional CSS box.
#theme-main-slider .item {
background-repeat: no-repeat;
height: auto !important;
}
#theme-main-slider .item {
padding-top: 40.56%;
display: block;
height: 0;
}
You can change the value of 40.56% as per the need for the height of slider image.
Let me know if it work.
Thanks
