Hello,
Currently, our button customization options only support the classic cart and checkout shortcodes included with the standard import of our theme (screenshot https://monosnap.com/file/9UKONbPPKouesnKd5YGJ9YleaSPeYM).
In the upcoming 8.1 update, we plan to add support for button styling in new WooCommerce cart/checkout Gutenberg blocks. For now, you can adjust the buttons using custom code, which should be added to the Global Custom CSS Area in Theme Settings.
.wc-block-cart__submit-container .wp-element-button,
.wc-block-checkout__actions_row .wc-block-components-checkout-place-order-button {
border-radius: var(--btn-accented-brd-radius);
color: var(--btn-accented-color);
box-shadow: var(--btn-accented-box-shadow);
background-color: var(--btn-accented-bgcolor);
text-transform: var(--btn-accented-transform, var(--btn-transform, uppercase));
font-weight: var(--btn-accented-font-weight, var(--btn-font-weight, 600));
font-family: var(--btn-accented-font-family, var(--btn-font-family, inherit));
font-style: var(--btn-accented-font-style, var(--btn-font-style, unset))
line-height: 1;
transition: all .25s ease !important;
}
.wc-block-cart__submit-container .wp-element-button:hover,
.wc-block-checkout__actions_row .wc-block-components-checkout-place-order-button:hover {
color: var(--btn-accented-color-hover);
box-shadow: var(--btn-accented-box-shadow-hover) !important;
background-color: var(--btn-accented-bgcolor-hover);
}
.wc-block-cart__submit-container .wp-element-button:active,
.wc-block-checkout__actions_row .wc-block-components-checkout-place-order-button:active {
box-shadow: var(--btn-accented-box-shadow-active) !important;
bottom: var(--btn-accented-bottom-active, 0);
}
Kind Regards
