Hi,

I'm having the same issue with my banner. I need it to be a slider banner but it's not resizing for mobile.

Thanks!

/* resize home mobile top banner */
@media screen and (max-width:767px) {
body.homepage article section:first-child {
    min-height: unset !important;
    height: 35vh;
    margin-top: 20vh;
}
}
