### Variants

The Input component supports two visual variants:

- **`primary`** (default) - Standard styling with shadow, suitable for most use cases
- **`secondary`** - Lower emphasis variant without shadow, suitable for use in Surface components

### In Surface

When used inside a [Surface](/systems/heroui/docs/components/surface) component, use `variant="secondary"` to apply the lower emphasis variant suitable for surface backgrounds.

## Styling

### Passing Tailwind CSS classes

```tsx
import {Input, Label} from '@heroui/react';

function CustomInput() {
  return (
    <div className="flex flex-col gap-2">
      <Label htmlFor="custom-input">Project name</Label>
      <Input
        id="custom-input"
        className="rounded-xl border border-border/70 bgsurface px-4 py-2 text-sm shadow-sm focus-visible:border-primary"
        placeholder="New web app"
      />
    </div>
  );
}
```

### Customizing the component classes

The base class `.input` powers every instance. Override it once with `@layer components`.

```css
@layer components {
  .input {
    @apply rounded-lg border border-border bgsurface px-4 py-2 text-sm shadow-sm transition-colors;

    &:hover,
    &[data-hovered="true"] {
      @apply bg-surface-secondary border-border/80;
    }

    &:focus-visible,
    &[data-focus-visible="true"] {
      @apply border-primary ring-2 ring-primary/20;
    }

    &[data-invalid="true"] {
      @apply border-danger bg-danger-50/10 text-danger;
    }
  }
}
```

### CSS Classes

- `.input` – Native input element styling

### Interactive States

- **Hover**: `:hover` or `[data-hovered="true"]`
- **Focus Visible**: `:focus-visible` or `[data-focus-visible="true"]`
- **Invalid**: `[data-invalid="true"]` (also syncs with `aria-invalid`)
- **Disabled**: `:disabled` or `[aria-disabled="true"]`
- **Read Only**: `[aria-readonly="true"]`

## API Reference

| `type` | `string` | `"text"` | Input type (text, email, password, number, etc.). |
| `value` | `string` | - | Controlled value. |
| `defaultValue` | `string` | - | Uncontrolled initial value. |
| `onChange` | `(event: React.ChangeEvent) => void` | - | Change handler. |
| `placeholder` | `string` | - | Placeholder text. |
| `disabled` | `boolean` | `false` | Disables the input. |
| `readOnly` | `boolean` | `false` | Makes the input read-only. |
| `required` | `boolean` | `false` | Marks the input as required. |
