Hi,
1. You can change columns on responsive https://prnt.sc/to8443
2. You should use custom class and add style for it. E.g:
@media (min-width: 1024px){
.vc_custom_1595546042694 {
border-right-width: 1px !important;
padding-top: 3vw !important;
padding-right: 3vw !important;
padding-bottom: 3vw !important;
padding-left: 2vw !important;
background-color: #2fa0cd !important;
border-right-color: #2fa0cd !important;
border-right-style: solid !important;
border-radius: 20px !important;
}
}
And remove custom style https://prnt.sc/to85ac
