I am using the spotflight theme and I have an image banner that looks fine on desktop but has a grey block under it when used on mobile. I managed to change this grey block to white and on the preview for the mobile site on shopify it looks like I fixed the issue; however, when I actually load the mobile website the grey block is still there despite me having fixed the issue on the mobile preview on the desktop by editing the code. I have already added all of the below to the base.CSS code to try and fix the issue:
}
@media screen and (max-width: 749px){
.password .banner__media {
position: absolute !important;
}
.banner__media.media {
background: white;
}
@media only screen and (max-width: 749px) {
.product-image-wrapper img {
opacity: 0 !important;
}
.card–card, .card–standard .card__inner {
background: transparent !important;
}
}
