* ### Styling
*
* The following shadow DOM parts are available for styling:
*
* Part name | Description
* ---------------------|----------------
* `label` | The slotted label element wrapper
* `helper-text` | The slotted helper text element wrapper
* `error-message` | The slotted error message element wrapper
* `required-indicator` | The `required` state indicator element
*
* The following state attributes are available for styling:
*
* Attribute | Description | Part name
* --------------------|-------------------------------------------|------------
* `disabled` | Set when the element is disabled | :host
* `focused` | Set when the element is focused | :host
* `focus-ring` | Set when the element is keyboard focused | :host
* `readonly` | Set when the element is readonly | :host
* `invalid` | Set when the element is invalid | :host
* `has-label` | Set when the element has a label | :host
* `has-value` | Set when the element has a value | :host
* `has-helper` | Set when the element has helper text | :host
* `has-error-message` | Set when the element has an error message | :host
*
* ### Internal components
*
* The following components are created by `` and placed in light DOM:
*
* - [``](#/elements/vaadin-date-picker).
* - [``](#/elements/vaadin-time-picker).
*
* Note: the `theme` attribute value set on `` is
* propagated to these components.
*
* See [Styling Components](https://vaadin.com/docs/latest/styling/styling-components) documentation.
*
* @fires {Event} change - Fired when the user commits a value change.
* @fires {CustomEvent} invalid-changed - Fired when the `invalid` property changes.
* @fires {CustomEvent} value-changed - Fired when the `value` property changes.
* @fires {CustomEvent} validated - Fired whenever the field is validated.
