 * ⚙️ **Customizable** – React Aria offers a flexible and scalable API that lets you dive as deep into the details as you like. Start with high-level components with a built-in DOM structure and simple styling API, compose custom patterns with contexts, and for the ultimate control, drop down to the low-level Hook-based API. Mix and match as needed.

The numbering system is automatically detected from user input, and input method editors such as Pinyin are supported.
 * **Validation** – Keyboard input is validated as the user types so that only numeric input is accepted, according to the locale and numbering system. Values are automatically rounded and clamped according to configurable decimal, minimum, maximum, and step values. Custom client and server-side validation is also supported.
 * **Mobile friendly** – An appropriate software keyboard is automatically selected based on the allowed values for ease of use.
 * **Accessible** – Follows the [spinbutton](https://www.w3.org/WAI/ARIA/apg/patterns/spinbutton/) ARIA pattern, with support for arrow keys, scroll wheel, and stepper buttons to increment and decrement the value. Extensively tested across many devices and [assistive technologies](accessibility.html#testing) to ensure announcements and behaviors are consistent.
