disable responsive mobile design

I'd like to disable my mobile design for my site cause the first photo (full bleed cover) doesn't show when I am on my mobile

Please help on a custom CSS, it's urgent 🙂

It looks like you figured it out with this code

@media screen and (max-width: 991px) {
    body.homepage #page section:first-child {
        min-height:40vh !important
    }
}

@media screen and (max-width: 767px) {
    body.homepage #page section:first-child {
        min-height:20vh !important
    }
}
