If you want to hide the 'add to cart' button on individual products amend the code so that the description after the .tag- is something like hidecart and then tag whatever product you want to remove 'add to cart' with 'hidecart'. You can change this wording to whatever you like but always keep the .tag- part.
For example:
/* Hide the add-to-cart button */
.tag-hidecart .ProductItem-summary .ProductItem-details {
.sqs-add-to-cart-button-wrapper, .product-quantity-input {
display: none;
}
}
Hopefully my amendment should work. Thanks to SF Digital for the original code.
Add the following to Website > Pages > Website Tools > Custom CSS.
.mobile-style-nav #block-yui_3_17_2_1_1592486068357_51634 .sqs-gallery-block-grid .slide:nth-last-child( 2 ) {
display : none;
}
Let us know how it goes.
