/**
 * `<vaadin-text-area>` is a Web Component for text area control in forms.
 *
 * ```html
 * <vaadin-text-area label="Add description">
 * </vaadin-text-area>
 * ```
 *
 * ### Prefixes and suffixes
 *
 * These are child elements of a `<vaadin-text-area>` that are displayed
 * inline with the input, before or after.
 * In order for an element to be considered as a prefix, it must have the slot
 * attribute set to `prefix` (and similarly for `suffix`).
 *
 * ```html
 * <vaadin-text-area label="Add description">
 *   <div slot="prefix">Details:</div>
 *   <div slot="suffix">The end!</div>
 * </vaadin-text-area>
 * ```
 *
 * ### Styling
 *
 * The following shadow DOM parts are available for styling:
 *
 * Part name | Description
 * ----------------|----------------
 * `label` | The label element
 * `input-field` | The element that wraps prefix, value and suffix
 * `value` | The text value element inside the `input-field` element
 * `error-message` | The error message element
 *
 * The following state attributes are available for styling:
 *
 * Attribute    | Description | Part name
 * -------------|-------------|------------
 * `disabled` | Set to a disabled text field | :host
 * `has-value` | Set when the element has a value | :host
 * `has-label` | Set when the element has a label | :host
 * `has-helper` | Set when the element has helper text | :host
 * `has-error-message` | Set when the element has an error message | :host
 * `invalid` | Set when the element is invalid | :host
 * `focused` | Set when the element is focused | :host
 * `focus-ring` | Set when the element is keyboard focused | :host
 * `readonly` | Set to a readonly text field | :host
 *
 * See [ThemableMixin – how to apply styles for shadow parts](https://github.com/vaadin/vaadin-themable-mixin/wiki)
