The remove from cart button I believe would be better positioned to the right of the product. It went there after I removed the quantity selector. Additionally the price of the product appears twice for some reason.
@amazingmaps please add this css to the very end of your base.css file and check,
Shopify Admin → Online Store ->Theme → Edit code → base.css
@media screen and (max-width: 749px) {
.cart-item__discounted-prices .cart-item__old-price {display: none !important;}
.cart-item__quantity {grid-column: 4 / 5; margin-top: -100px;}
}
@amazingmaps add !important after 4/5 an check, so code becomes
@media screen and (max-width: 749px) {
.cart-item__discounted-prices .cart-item__old-price {display: none !important;}
.cart-item__quantity {grid-column: 4 / 5 !important; margin-top: -100px;}
}
@amazingmaps I pasted updated code in above reply
@amazingmaps great
