woocommerce absolute button bottom

Hello, I need your help to be able to align the add-to-cart buttons, please indicate where I can go, I have this code but I do not know what CSS I can leave it

a.added_to_cart.wc-forward {
     bottom: 0;
     position: absolute;
     display: block;
     bottom: 0px;
}

.woocommerce ul.products li.product,
.woocommerce-page ul.products li.product {
     min-height: 295px! important;
     margin-bottom: 10px;
}

a.button.add_to_cart_button,
a.button.product_type_simple {
     bottom: 30px;
     position: absolute;
}

Thank you very much
