Hello, Steven Tay,
Try to change this code https://prnt.sc/4lSiYY_kPhzw to:
.woocommerce-checkout .payment_methods {
text-align: center;
}
.woocommerce-checkout .ppcp-button-container {
min-width: unset;
}
.woocommerce-checkout .payment_box {
padding-left: 0px;
}
.woocommerce-checkout #shipping_method li {
flex-wrap: wrap;
position: relative;
}
.woocommerce-checkout #payment .payment_methods label, .woocommerce-checkout #shipping_method label {
max-width: calc(100% - 20px);
}
.woocommerce-checkout #payment .payment_methods input[type=radio], .woocommerce-checkout #shipping_method input[type=radio] {
float: left;
}
Kind Regards,
