Hi,
I don't know why but everything worked except my item title & checkout Button. Bellow is my css code, let me know what went wrong
.cart-title, .cart-item-list-labels, .item-desc, .variant-name, .item-quantity, .item-price, .vP_HqHxwY, .TPEfWzjos, .sqs-editable-button KD_Juh_j6 checkout-button, {
font-size: 1em !important;
}
