##&lt;gold-zip-input&gt;


`gold-zip-input` is a single-line text field with Material Design styling
for entering a US zip code.

    <gold-zip-input></gold-zip-input>

It may include an optional label, which by default is "Zip Code".

    <gold-zip-input label="Mailing zip code"></gold-zip-input>

### Validation

The input supports both 5 digit zip codes (90210) or the full 9 digit ones,
separated by a dash (90210-9999).

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.
