Sometimes height and min-height will not work on ipad and safari browsers. You can use display:flex follow flexbox group to align equal column height as below example.
.row.mycolspce div[class^="col-"] {
display: flex;
flex-wrap: wrap;
}
.feature-imgitem img {
object-fit:cover;
}
.feature-imgitem,.banner_effect {
display:flex;
}
