Thanks Made4Uo.
So
.product-form__controls-group ~ .product-form__controls-group–submit { margin-top: 0 !important; visibility: hidden !important; height: 0 !important; }
at theme.css under Asset, and then
.hide-buttons {
margin-top: 0 !important;
visibility: hidden !important;
height: 0 !important;
}
inside the class " product-form__controls-group" in my specific product page??? How to find such page under “edit code”?? Or do I go to the editing interface of that specific product? Sorry for my stupid questions. I’m not too familiar with these..
