Hi there,
the Site you imported uses some Additional CSS in the Customizer. These two parts are what changes the button to a link and creates the hover effect. Remove that code:
.woocommerce ul.products li.product a.button {
padding: 5px 0;
color: inherit;
background-color: #ffffff;
text-transform: uppercase;
}
/* Transform add to cart and pricing on hover */
@media (min-width: 768px) {
.woocommerce ul.products li.product a.button {
transform: translateY(0);
width: 100%;
opacity: 0;
transition: all 0.4s;
}
.woocommerce ul.products li.product:hover a.button,
.woocommerce ul.products li.product:hover .price {
transform: translateY(calc(-100% - 10px));
opacity: 1;
}
.woocommerce ul.products li.product .price {
opacity: 1;
transition: all 0.4s;
}
.woocommerce ul.products li.product:hover .price {
opacity: 0;
transform: translateY(calc(-100% - 10px));
}
}
