[](https://travis-ci.org/PolymerElements/gold-zip-input) _[Demo and API Docs](https://elements.polymer-project.org/elements/gold-zip-input)_ ##<gold-zip-input> `gold-zip-input` is a single-line text field with Material Design styling for entering a US zip code. It may include an optional label, which by default is "Zip Code". ### 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.
