It works like this! thanks a lot! @tuanphan
I had to make a little twist.
@media screen and (max-width:767px) {
[data-section-id="63987d07c71b4732240d4058"] .section-background * {
visibility: hidden !important;
}
}
@media only screen and (max-width: 767px){
[data-section-id="63987d07c71b4732240d4058"] .section-background {
background-image: url(https://static1.squarespace.com/static/63987c03bf68e244c3d2b2ce/t/63bc4a45670e3049b76acef1/1673284168258/Invitation-Vertical.jpg);
background-size: cover;
background-position: center;
background-repeat: no-repeat;
}
}
