| 20 `gold-cc-cvc-input` is a single-line text field with Material Design styling |
| 21 for entering a credit card's CVC (Card Verification Code). It supports both |
| 22 4-digit Amex CVCs and non-Amex 3-digit CVCs |
| 23 |
| 24 <gold-cc-cvc-input></gold-cc-cvc-input> |
| 25 |
| 26 <gold-cc-cvc-input card-type="amex"></gold-cc-cvc-input> |
| 27 |
| 28 It may include an optional label, which by default is "CVC". |
| 29 |
| 30 <gold-cc-cvc-input label="Card Verification Value"></gold-cc-cvc-input> |
| 31 |
| 32 It can be used together with a `gold-cc-input` by binding the `cardType` propert
y: |
| 33 |
| 34 <gold-cc-input card-type="{{cardType}}"></gold-cc-input> |
| 35 <gold-cc-cvc-input card-type="[[cardType]]"></gold-cc-cvc-input> |
| 36 |
| 37 ### Validation |
| 38 |
| 39 The input considers a valid amex CVC to be 4 digits long, and 3 digits otherwise
. |
| 40 The `amex` attribute can also be bound to a `gold-cc-input`'s `card-type` attrib
ute. |
| 41 |
| 42 The input can be automatically validated as the user is typing by using |
| 43 the `auto-validate` and `required` attributes. For manual validation, the |
| 44 element also has a `validate()` method, which returns the validity of the |
| 45 input as well sets any appropriate error messages and styles. |
| 46 |
| 47 See `Polymer.PaperInputBehavior` for more API docs. |
| 48 |
| 49 ### Styling |
| 50 |
| 51 See `Polymer.PaperInputContainer` for a list of custom properties used to |
| 52 style this element. |
