Will add mobile layout for artist section to solve this problem

Will add above rule for artists pictures compatible with screen 768px - 970px and less than 768px width

Already updated layout code and fixed this problem. Thanks

@media (min-width:992px) {
    .col-md-4 {
        width: 33.3333%;
    }
}
@media (min-width: 768px) {
    .col-md-4 {
        width: 33.1%;
    }
}
@media (max-width: 767px) {
    .col-md-4 {
        width: 100%;
    }
}
