# Meter

A high-quality, unstyled Solid meter component that provides a graphical display of a numeric value.

## Demo

### Tailwind

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

```tsx
/* index.tsx */
import { Meter } from 'base-ui-solid/meter';

export default function ExampleMeter() {
  return (
    <Meter.Root class="grid max-w-full w-60 grid-cols-2 gap-y-2" value={24}>
      <Meter.Label class="text-sm font-normal text-neutral-950 dark:text-white">
        Storage Used
      </Meter.Label>
      <Meter.Value class="text-right text-sm text-neutral-950 dark:text-white" />
      <Meter.Track class="col-span-2 h-3 overflow-hidden bg-neutral-200 dark:bg-neutral-800">
        <Meter.Indicator class="bg-neutral-950 transition-[width] duration-500 dark:bg-white" />
      </Meter.Track>
    </Meter.Root>
  );
}
```

### CSS Modules

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

```css
/* index.module.css */
.Meter {
  display: grid;
  grid-template-columns: 1fr 1fr;
  row-gap: 0.5rem;
  width: 15rem;
  max-width: 100%;
}

.Label {
  font-size: 0.875rem;
  line-height: 1.25rem;
  font-weight: 400;
  color: oklch(14.5% 0 0deg);

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

.Value {
  font-size: 0.875rem;
  line-height: 1.25rem;
  color: oklch(14.5% 0 0deg);
  text-align: right;

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

.Track {
  grid-column: 1 / 3;
  overflow: hidden;
  height: 0.75rem;
  background-color: oklch(92.2% 0 0deg);

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

.Indicator {
  background-color: oklch(14.5% 0 0deg);
  transition: width 500ms;

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

```tsx
/* index.tsx */
import { Meter } from 'base-ui-solid/meter';
import styles from './index.module.css';

export default function ExampleMeter() {
  return (
    <Meter.Root class={styles.Meter} value={24}>
      <Meter.Label class={styles.Label}>Storage Used</Meter.Label>
      <Meter.Value class={styles.Value} />
      <Meter.Track class={styles.Track}>
        <Meter.Indicator class={styles.Indicator} />
      </Meter.Track>
    </Meter.Root>
  );
}
```

## Anatomy

Import the component and assemble its parts:

```jsx title="Anatomy"
import { Meter } from 'base-ui-solid/meter';

<Meter.Root>
  <Meter.Label />
  <Meter.Track>
    <Meter.Indicator />
  </Meter.Track>
