##&lt;gold-cc-expiration-input&gt;


`gold-cc-expiration-input` is a  single-line text field with Material Design styling
for entering a credit card's expiration date

    <gold-cc-expiration-input></gold-cc-expiration-input>
    <gold-cc-expiration-input value="11/15"></gold-cc-expiration-input>

It may include an optional label, which by default is "Expiration Date".

    <gold-cc-expiration-input label="Date"></gold-cc-expiration-input>


### Validation

The input can check whether the entered date is a valid, future date.

The input can be automatically validated as the user is typing by using
the `auto-validate` and `required` attributes. For manual validation, the
element also has a `validate()` method, which returns the validity of the
input as well sets any appropriate error messages and styles.

See `Polymer.PaperInputBehavior` for more API docs.

### Styling

See `Polymer.PaperInputContainer` for a list of custom properties used to
style this element.
