Hello Christoph Berz
Please use this CSS to
Template Options -> Custom Code -> Custom CSS
@media(max-width: 425px){
.sp-simpleportfolio .sp-simpleportfolio-item .sp-simpleportfolio-overlay{
opacity: 1 !important;
}
.sp-simpleportfolio .sp-simpleportfolio-item .sp-simpleportfolio-img{
-webkit-transform: scale3d(1.15, 1.15, 1) !important;
transform: scale3d(1.15, 1.15, 1) !important;
}
.sp-simpleportfolio .sp-simpleportfolio-item .sp-simpleportfolio-btns a{
opacity: 1 !important;
-webkit-transform: scale3d(1, 1, 1) !important;
transform: scale3d(1, 1, 1) !important;
}
.sp-simpleportfolio .sp-simpleportfolio-item .sp-vertical-middle .sp-simpleportfolio-tags,
.sp-simpleportfolio .sp-simpleportfolio-item .sp-vertical-middle .sp-simpleportfolio-title{
opacity: 1 !important;
-webkit-transform: translate3d(0, 0, 0) !important;
transform: translate3d(0, 0, 0) !important;
}
}
Then on the mobile devices, the options will be visible without touching or pressing the images.
Best regards
