Hello,

Try to add the following code in Theme Settings > Custom CSS > Global Custom CSS:

.page-id-291 .wd-add-btn-replace .add-to-cart-loop {
      width: -webkit-fill-available;
    background-color: #0f8c11;
}
 .page-id-291 .product.wd-hover-fw-button .wd-add-btn .add-to-cart-loop span {
color: white;
}

Best Regards.
