# Textarea

A native textarea element that automatically works with Field.

## Demo

### Tailwind

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

```svelte
<!-- index.svelte -->
<script lang="ts">
	import { Textarea } from '@sveltery/base/textarea';
</script>

<label class="flex flex-col items-start gap-1 text-sm font-bold text-neutral-950 dark:text-white">
	Message
	<Textarea
		placeholder="Write a message"
		rows={3}
		class="w-56 border border-neutral-950 dark:border-white bg-white dark:bg-neutral-950 px-2 py-1 text-sm any-pointer-coarse:text-base font-normal text-neutral-950 dark:text-white placeholder:text-neutral-500 dark:placeholder:text-neutral-400 focus:outline-2 focus:-outline-offset-1 focus:outline-neutral-950 dark:focus:outline-white"
	/>
</label>
```

### CSS Modules

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

```css
/* index.module.css */
.Label {
	display: flex;
	flex-direction: column;
	align-items: flex-start;
	gap: 0.25rem;
	font-size: 0.875rem;
	line-height: 1.25rem;
	font-weight: 700;
	color: oklch(14.5% 0 0deg);

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

.Textarea {
	box-sizing: border-box;
	padding: 0.25rem 0.5rem;
	margin: 0;
	border-radius: 0;
	border: 1px solid oklch(14.5% 0 0deg);
	width: 14rem;
	font-family: inherit;
	font-size: 0.875rem;
	line-height: 1.25rem;
	font-weight: 400;
	background-color: white;
	color: oklch(14.5% 0 0deg);

	@media (any-pointer: coarse) {
		font-size: 1rem;
		line-height: 1.5rem;
	}

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

	&::placeholder {
		color: oklch(55.6% 0 0deg);

		@media (prefers-color-scheme: dark) {
			color: oklch(70.8% 0 0deg);
		}
	}

	&:focus {
		outline: 2px solid oklch(14.5% 0 0deg);
		outline-offset: -1px;

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

```svelte
<!-- index.svelte -->
<script lang="ts">
	import { Textarea } from '@sveltery/base/textarea';
	import styles from './index.module.css';
</script>

<label class={styles.Label}>
	Message
	<Textarea placeholder="Write a message" rows={3} class={styles.Textarea} />
</label>
```

## 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](/handbook/forms.md).

## Anatomy

Import the component and use it as a single part:

```svelte title="Anatomy"
<script lang="ts">
	import { Textarea } from '@sveltery/base/textarea';
</script>

<Textarea />
```

In a SvelteKit remote form, spread a field's `as('text')` props onto it. TypeScript rejects the props of any other input type, because a textarea has no `type`.

## API reference

### Textarea

A native textarea that works with [Field](https://base.sveltery.dev/components/field) the way Input does. Renders a `<textarea>` element. Sveltery addition, with no Base UI counterpart. It declares `type?: never`, so a remote form spread of another input kind is a type error.

**Textarea Props:**

| Prop         | Type                                                                                             | Default | Description                                                                                                                                                                                                                             |
