### Tailwind

This example shows how to implement the component using Tailwind CSS.

## Usage guidelines

- **Form controls must have an accessible name**: It can be created using a `<label>` element or the `Field` component. See the [forms guide](/react/handbook/forms.md).

## Anatomy

Import the component and assemble its parts:

```jsx title="Anatomy"
import { NumberField } from '@base-ui/react/number-field';

<NumberField.Root>
  <NumberField.ScrubArea>
    <NumberField.ScrubAreaCursor />
  </NumberField.ScrubArea>
  <NumberField.Group>
    <NumberField.Decrement />
    <NumberField.Input />
    <NumberField.Increment />
  </NumberField.Group>
</NumberField.Root>;
```

## Examples

### Controlling the input text

`value` holds the parsed number, so it can't represent text that isn't a number yet.
Typing `-1.5` passes through `-` and `-1.`, neither of which parses, and both leave `value` untouched.

To drive those intermediate states, control the raw text with `inputValue`, `defaultInputValue`, and `onInputValueChange`.
It's independent of `value`, so both can be controlled at once:

```tsx title="Controlling the input text"
const [value, setValue] = React.useState<number | null>(null);
const [inputValue, setInputValue] = React.useState('');

<NumberField.Root
  min={-100}
  value={value}
  onValueChange={setValue}
  // @highlight-start
  inputValue={inputValue}
  onInputValueChange={setInputValue}
  // @highlight-end
>
  {/* ... */}
</NumberField.Root>;

// Puts the field into a valid intermediate state that `value` cannot express.
setInputValue('-');
```

The text is never formatted or clamped on the way in, so any string is allowed.
`onInputValueChange` reports the text two ways. Typing, clearing, and pasting report the raw string verbatim — `input-change`, `input-clear`, and `input-paste` carry exactly what the user produced, with no formatting applied. Blur, stepping, and the `'none'` reason instead propose formatted text, the last of these after an external `value`, `locale`, or `format` change.
Mirroring every call back into `inputValue` reproduces the uncontrolled behavior. Every call must be answered: mirror it, or refuse it with `eventDetails.cancel()`. Refusing a formatted proposal keeps your own text, and refusing an `input-change` call vetoes the keystroke outright rather than preserving anything. Ignoring a call is neither — the text stays as it was while the rest of the change goes through, so the field can end up showing one number and reporting another.

Intermediate states are transient by design. Blur reconciles any text that isn't a number back to `value` under `'input-blur'`, whether the user typed it or you set it yourself — so a `'-'` you installed programmatically is proposed away as soon as the field is focused and left, even with no edits in between. Refuse the `'input-blur'` call to keep it.

## API reference

### Root

Groups all parts of the number field and manages its state.
Renders a `<div>` element.

**Root Props:**

| Prop               | Type                                                                                           | Default | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |

### ScrubAreaCursor

A custom element to display instead of the native cursor while using the scrub area.
Renders a `<span>` element.

This component uses the [Pointer Lock API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API), which may prompt the browser to display a related notification. It is disabled
in Safari to avoid a layout shift that this notification causes there.
