Woocommerce remove the Add To Cart and View Details hover buttons from prod imgs

Hi guys, how can I remove those two hover buttons from the woocommerce product images? Currently I tried googling and added the following codes to the Custom CSS section of the Highend Theme:

button-mini-delimiter { display: none !important; }
.show_details_button {
    display: none !important;
}

.action .add_to_cart_button { display: none !important; }

But nothing has worked yet. Any ideas?
