/**
* \@name Input
* \@description
*
* `ion-input` is meant for text type inputs only, such as `text`,
* `password`, `email`, `number`, `search`, `tel`, and `url`. Ionic
* still uses an actual `<input type="text">` HTML element within the
* component, however, with Ionic wrapping the native HTML input
* element it's better able to handle the user experience and
* interactivity.
*
* Similarly, `<ion-textarea>` should be used in place of `<textarea>`.
*
* An `ion-input` is **not** used for non-text type inputs, such as a
* `checkbox`, `radio`, `toggle`, `range`, `select`, etc.
*
* Along with the blur/focus events, `input` support all standard text input
* events like `keyup`, `keydown`, `keypress`, `input`,etc. Any standard event
* can be attached and will function as expected.
*
* \@usage

/**
* @name TextArea
* @description
*
* `ion-textarea` is used for multi-line text inputs. Ionic still
* uses an actual `<textarea>` HTML element within the component;
* however, with Ionic wrapping the native HTML text area element, Ionic
* is able to better handle the user experience and interactivity.
*
* Note that `<ion-textarea>` must load its value from the `value` or
* `[(ngModel)]` attribute. Unlike the native `<textarea>` element,
* `<ion-textarea>` does not support loading its value from the
* textarea's inner content.
*
* When requiring only a single-line text input, we recommend using
* `<ion-input>` instead.
*
* @usage
* ```html
* <ion-item>
* <ion-label>Comments</ion-label>
* <ion-textarea></ion-textarea>
* </ion-item>
*
* <ion-item>
* <ion-label stacked>Message</ion-label>
* <ion-textarea [(ngModel)]="msg"></ion-textarea>
* </ion-item>
*
* <ion-item>
* <ion-label floating>Description</ion-label>
* <ion-textarea></ion-textarea>
* </ion-item>
*
* <ion-item>
* <ion-label>Long Description</ion-label>
* <ion-textarea rows="6" placeholder="enter long description here..."></ion-textarea>
