## CardNumberElement

Use the `CardNumberElement` from `@stripe/react-stripe-js` to collect the PAN (primary account number) independently
while rendering Card CVC and expiration in separate Elements.

### Props

- `id`
  Sets the DOM `id` attribute on the rendered Element container. Use this to
target the Element for styling or testing.

- `className`
  Applies custom CSS classes to the Element container.

- `options`
  Options for creating a `cardNumber` element.
    - `classes`
      Set custom class names on the container DOM element when the Stripe element is in a particular state.
      - `base`
        The base class applied to the container.
Defaults to `StripeElement`.
      - `complete`
        The class name to apply when the `Element` is complete.
Defaults to `StripeElement--complete`.
      - `empty`
        The class name to apply when the `Element` is empty.
Defaults to `StripeElement--empty`.
      - `focus`
        The class name to apply when the `Element` is focused.
Defaults to `StripeElement--focus`.
      - `invalid`
        The class name to apply when the `Element` is invalid.
Defaults to `StripeElement--invalid`.
      - `webkitAutofill`
        The class name to apply when the `Element` has its value autofilled by the browser (only on Chrome and Safari).
Defaults to `StripeElement--webkit-autofill`.
    - `style`
      Customize the appearance of this element using CSS properties passed in a [Style](https://docs.stripe.com/js/appendix/style.md) object.
    - `placeholder`
      Customize the placeholder text.
    - `disabled`
      Applies a disabled state to the Element such that user input is not accepted.
Default is `false`.
    - `showIcon`
      Show a card brand icon in the Element.
Default is `false`.
    - `iconStyle`
      Appearance of the icon in the Element.
Either `solid` or `default`.
    - `disableLink`
      Disables and hides the Link button in the Element.
Default is `false`.
You can also disable Link across all instances of `card` and `cardNumber` elements in your [payment method settings](https://dashboard.stripe.com/settings/payment_methods).
    - `preferredNetwork`
      Specifies a network preference for [Card Brand Choice](https://docs.stripe.com/card-brand-choice.md). The first network in the array that matches a
network on the entered co-branded card will be selected by default in the Card Brand Choice dropdown. See the
[supported networks](https://docs.stripe.com/api/payment_methods/create.md#create_payment_method-card-networks-preferred) for valid values.

If you specify a value for `preferredNetwork` at create time, [showIcon](#elements_create-options-showIcon) must be true
(so that the Card Brand Choice dropdown can appear) and you cannot specify
[payment_method_options.card.network](https://docs.stripe.com/js/payment_intents/confirm_card_payment.md#stripe_confirm_card_payment-data-payment_method_options-card-network)
at confirm time.
