# Slider

A high-quality, unstyled React slider component that works like a range input and is easy to style.

## Demo

### Tailwind

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

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';

export default function ExampleSlider() {
  return (
    <Slider.Root defaultValue={25}>
      <Slider.Control className="flex w-56 touch-none items-center py-3 select-none">
        <Slider.Track className="h-1 w-full bg-neutral-200 select-none dark:bg-neutral-800">
          <Slider.Indicator className="bg-neutral-950 select-none dark:bg-white" />
          <Slider.Thumb
            aria-label="Volume"
            className="size-4 border border-neutral-950 bg-white select-none has-[:focus-visible]:outline-2 has-[:focus-visible]:outline-offset-2 has-[:focus-visible]:outline-neutral-950 dark:has-[:focus-visible]:outline-white dark:border-white dark:bg-neutral-950"
          />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### CSS Modules

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

```css
/* index.module.css */
.Control {
  box-sizing: border-box;
  display: flex;
  align-items: center;
  width: 14rem;
  padding-block: 0.75rem;
  touch-action: none;
  -webkit-user-select: none;
  user-select: none;
}

.Track {
  width: 100%;
  height: 0.25rem;
  background-color: oklch(92.2% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: oklch(26.9% 0 0deg);
  }
}

.Indicator {
  background-color: oklch(14.5% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: white;
  }
}

.Thumb {
  box-sizing: border-box;
  width: 1rem;
  height: 1rem;
  border: 1px solid oklch(14.5% 0 0deg);
  background-color: white;
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    border: 1px solid white;
    background-color: oklch(14.5% 0 0deg);
  }

  &:has(:focus-visible) {
    outline: 2px solid oklch(14.5% 0 0deg);
    outline-offset: 2px;

    @media (prefers-color-scheme: dark) {
      outline-color: white;
    }
  }
}
```

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';
import styles from './index.module.css';

export default function ExampleSlider() {
  return (
    <Slider.Root defaultValue={25}>
      <Slider.Control className={styles.Control}>
        <Slider.Track className={styles.Track}>
          <Slider.Indicator className={styles.Indicator} />
          <Slider.Thumb aria-label="Volume" className={styles.Thumb} />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

## Usage guidelines

- **Form controls must have an accessible name**: Prefer `<Slider.Label>`, or provide an `aria-label` on each `<Slider.Thumb>` when no visible label is rendered. See [Labeling a slider](/react/components/slider.md) and the [forms guide](/react/handbook/forms.md).

## Anatomy

Import the component and assemble its parts:

```jsx title="Anatomy"
import { Slider } from '@base-ui/react/slider';

<Slider.Root>
  <Slider.Label />
  <Slider.Value />
  <Slider.Control>
    <Slider.Track>
      <Slider.Indicator />
      <Slider.Thumb />
    </Slider.Track>
  </Slider.Control>
</Slider.Root>;
```

## Examples

### Range slider

To create a range slider:

1. Pass an array of values and place a `<Slider.Thumb>` for each value in the array
2. Additionally for server-side rendering, specify a numeric `index` for each thumb that corresponds to the index of its value in the value array

Thumbs can be configured to behave differently when they collide during pointer interactions using the `thumbCollisionBehavior` prop on `<Slider.Root>`.

## Demo

### Tailwind

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

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';

export default function RangeSlider() {
  return (
    <Slider.Root defaultValue={[25, 45]}>
      <Slider.Control className="flex w-56 touch-none items-center py-3 select-none">
        <Slider.Track className="h-1 w-full bg-neutral-200 select-none dark:bg-neutral-800">
          <Slider.Indicator className="bg-neutral-950 select-none dark:bg-white" />
          <Slider.Thumb
            index={0}
            aria-label="Minimum value"
            className="size-4 border border-neutral-950 bg-white select-none has-[:focus-visible]:outline-2 has-[:focus-visible]:outline-offset-2 has-[:focus-visible]:outline-neutral-950 dark:has-[:focus-visible]:outline-white dark:border-white dark:bg-neutral-950"
          />
          <Slider.Thumb
            index={1}
            aria-label="Maximum value"
            className="size-4 border border-neutral-950 bg-white select-none has-[:focus-visible]:outline-2 has-[:focus-visible]:outline-offset-2 has-[:focus-visible]:outline-neutral-950 dark:has-[:focus-visible]:outline-white dark:border-white dark:bg-neutral-950"
          />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### CSS Modules

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

```css
/* index.module.css */
.Control {
  box-sizing: border-box;
  display: flex;
  align-items: center;
  width: 14rem;
  padding-block: 0.75rem;
  touch-action: none;
  -webkit-user-select: none;
  user-select: none;
}

.Track {
  width: 100%;
  height: 0.25rem;
  background-color: oklch(92.2% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: oklch(26.9% 0 0deg);
  }
}

.Indicator {
  background-color: oklch(14.5% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: white;
  }
}

.Thumb {
  box-sizing: border-box;
  width: 1rem;
  height: 1rem;
  border: 1px solid oklch(14.5% 0 0deg);
  background-color: white;
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    border: 1px solid white;
    background-color: oklch(14.5% 0 0deg);
  }

  &:has(:focus-visible) {
    outline: 2px solid oklch(14.5% 0 0deg);
    outline-offset: 2px;

    @media (prefers-color-scheme: dark) {
      outline-color: white;
    }
  }
}
```

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';
import styles from './index.module.css';

export default function RangeSlider() {
  return (
    <Slider.Root defaultValue={[25, 45]}>
      <Slider.Control className={styles.Control}>
        <Slider.Track className={styles.Track}>
          <Slider.Indicator className={styles.Indicator} />
          <Slider.Thumb index={0} aria-label="Minimum value" className={styles.Thumb} />
          <Slider.Thumb index={1} aria-label="Maximum value" className={styles.Thumb} />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### Thumb alignment

Set `thumbAlignment="edge"` to inset the thumb such that its edge aligns with the edge of the control when the value is at `min` or `max`, without overflowing the control like the default `"center"` alignment.

A client-only alternative `thumbAlignment="edge-client-only"` can be used to reduce bundle size but only renders after React hydration.

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';

export default function EdgeAlignedThumb() {
  return (
    <Slider.Root thumbAlignment="edge" defaultValue={25}>
      <Slider.Control className="flex w-56 touch-none items-center py-3 select-none">
        <Slider.Track className="h-1 w-full bg-neutral-200 select-none dark:bg-neutral-800">
          <Slider.Indicator className="bg-neutral-950 select-none dark:bg-white" />
          <Slider.Thumb
            aria-label="Volume"
            className="size-4 border border-neutral-950 bg-white select-none has-[:focus-visible]:outline-2 has-[:focus-visible]:outline-offset-2 has-[:focus-visible]:outline-neutral-950 dark:has-[:focus-visible]:outline-white dark:border-white dark:bg-neutral-950"
          />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

.Control {
  box-sizing: border-box;
  display: flex;
  align-items: center;
  width: 14rem;
  padding-block: 0.75rem;
  touch-action: none;

  border: 1px solid oklch(14.5% 0 0deg);
  background-color: white;

  }

  &:has(:focus-visible) {
    outline: 2px solid oklch(14.5% 0 0deg);
    outline-offset: 2px;

    @media (prefers-color-scheme: dark) {
      outline-color: white;
    }
  }
}
```

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';
import styles from './index.module.css';

export default function EdgeAlignedThumb() {
  return (
    <Slider.Root thumbAlignment="edge" defaultValue={25}>
      <Slider.Control className={styles.Control}>
        <Slider.Track className={styles.Track}>
          <Slider.Indicator className={styles.Indicator} />
          <Slider.Thumb aria-label="Volume" className={styles.Thumb} />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### Labeling a slider

A single-thumb slider without a visible label (such as a volume control) can be labeled using `aria-label` on `<Slider.Thumb>`:

```tsx title="Slider with invisible label"
<Slider.Root>
  <Slider.Control>
    <Slider.Track>
      <Slider.Indicator />
      {/* @highlight */}
      <Slider.Thumb aria-label="Volume" />
    </Slider.Track>
  </Slider.Control>
</Slider.Root>
```

A visible label can be created using `<Slider.Label>`:

```tsx title="Slider with visible label"
<Slider.Root>
  {/* @highlight */}
  <Slider.Label>Volume</Slider.Label>
  <Slider.Control>
    <Slider.Track>
      <Slider.Indicator />
      <Slider.Thumb />
    </Slider.Track>
  </Slider.Control>
</Slider.Root>
```

For a multi-thumb range slider with a visible label, add `aria-label` on each `<Slider.Thumb>` to distinguish them:

```tsx title="Labeling multi-thumb range sliders"
<Slider.Root defaultValue={[25, 75]}>
  <Slider.Label>Price range</Slider.Label>
  <Slider.Control>
    <Slider.Track>
      <Slider.Indicator />
      {/* @highlight-start */}
      <Slider.Thumb index={0} aria-label="Minimum price" />
      <Slider.Thumb index={1} aria-label="Maximum price" />
      {/* @highlight-end */}
    </Slider.Track>
  </Slider.Control>
</Slider.Root>
```

### Vertical

Set `orientation="vertical"` on `<Slider.Root>` to build a vertical slider.

## Demo

### Tailwind

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

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';

export default function VerticalSlider() {
  return (
    <Slider.Root orientation="vertical" defaultValue={35}>
      <Slider.Control className="flex touch-none select-none data-[orientation=vertical]:h-32 data-[orientation=vertical]:px-3">
        <Slider.Track className="bg-neutral-200 select-none dark:bg-neutral-800 data-[orientation=vertical]:h-full data-[orientation=vertical]:w-1">
          <Slider.Indicator className="bg-neutral-950 select-none dark:bg-white" />
          <Slider.Thumb
            aria-label="Volume"
            className="size-4 border border-neutral-950 bg-white select-none has-[:focus-visible]:outline-2 has-[:focus-visible]:outline-offset-2 has-[:focus-visible]:outline-neutral-950 dark:has-[:focus-visible]:outline-white dark:border-white dark:bg-neutral-950"
          />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### CSS Modules

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

```css
/* index.module.css */
.Control {
  box-sizing: border-box;
  display: flex;
  touch-action: none;
  -webkit-user-select: none;
  user-select: none;

  &[data-orientation='vertical'] {
    height: 8rem;
    padding-inline: 0.75rem;
  }
}

.Track {
  background-color: oklch(92.2% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: oklch(26.9% 0 0deg);
  }

  &[data-orientation='vertical'] {
    height: 100%;
    width: 0.25rem;
  }
}

.Indicator {
  background-color: oklch(14.5% 0 0deg);
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    background-color: white;
  }
}

.Thumb {
  box-sizing: border-box;
  width: 1rem;
  height: 1rem;
  border: 1px solid oklch(14.5% 0 0deg);
  background-color: white;
  -webkit-user-select: none;
  user-select: none;

  @media (prefers-color-scheme: dark) {
    border: 1px solid white;
    background-color: oklch(14.5% 0 0deg);
  }

  &:has(:focus-visible) {
    outline: 2px solid oklch(14.5% 0 0deg);
    outline-offset: 2px;

    @media (prefers-color-scheme: dark) {
      outline-color: white;
    }
  }
}
```

```tsx
/* index.tsx */
import { Slider } from '@base-ui/react/slider';
import styles from './index.module.css';

export default function VerticalSlider() {
  return (
    <Slider.Root orientation="vertical" defaultValue={35}>
      <Slider.Control className={styles.Control}>
        <Slider.Track className={styles.Track}>
          <Slider.Indicator className={styles.Indicator} />
          <Slider.Thumb aria-label="Volume" className={styles.Thumb} />
        </Slider.Track>
      </Slider.Control>
    </Slider.Root>
  );
}
```

### Form integration

To use a slider in a form, pass the slider `name` to `<Slider.Root>`:

```tsx title="Using Slider in a form"
<Form>
  {/* @highlight */}
  <Slider.Root name="volume">
    <Slider.Label>Volume</Slider.Label>
    <Slider.Control>
      <Slider.Track>
        <Slider.Indicator />
        <Slider.Thumb />
      </Slider.Track>
    </Slider.Control>
  </Slider.Root>
</Form>
```

For grouped multi-thumb range sliders in forms, [Fieldset](/react/components/fieldset.md) can provide the shared visible label while each thumb keeps its own `aria-label`:

```tsx title="Using Fieldset with a multi-thumb slider"
<Field.Root>
  {/* @highlight-start */}
  <Fieldset.Root render={<Slider.Root defaultValue={[25, 75]} />}>
    <Fieldset.Legend>Price range</Fieldset.Legend>
    {/* @highlight-end */}
    <Slider.Control>
      <Slider.Track>
        <Slider.Indicator />
        {/* @highlight-start */}
        <Slider.Thumb index={0} aria-label="Minimum price" />
        <Slider.Thumb index={1} aria-label="Maximum price" />
        {/* @highlight-end */}
      </Slider.Track>
    </Slider.Control>
  </Fieldset.Root>
</Field.Root>
```
