## Usage

<Steps>
  <Step title="Include CSS">

Import Tailwind and one full Basecoat style bundle.

```css
@import "tailwindcss";
@import "basecoat-css/vega.css";
```

Or import only the base CSS, Field component CSS, and one style pack.

```css
@import "tailwindcss";
@import "basecoat-css/base.css";
@import "basecoat-css/components/field.css";
@import "basecoat-css/styles/vega.css";
```

Using CDN or bundler imports? See the [Installation page](/installation).

  </Step>
  <Step title="Add your field HTML">

Use `class="field"` for one control and `class="fieldset"` for related controls. Use a native `<fieldset>` when the group needs a `<legend>`; otherwise use a labelled `role="group"`.

```html
<fieldset class="fieldset">
  <legend>Profile</legend>
  <p>This appears on invoices and emails.</p>
  <div role="group" aria-label="Profile fields">
    <div role="group" class="field">
      <label for="name">Full name</label>
      <input id="name" autocomplete="off" placeholder="Evil Rabbit" />
      <p>This appears on invoices and emails.</p>
    </div>
    <div role="group" class="field" data-invalid>
      <label for="username">Username</label>
      <input id="username" autocomplete="off" aria-invalid="true" aria-describedby="username-error" />
      <p id="username-error" role="alert">Choose another username.</p>
    </div>
    <div role="group" class="field" data-orientation="horizontal">
      <input id="newsletter" type="checkbox" role="switch" />
      <label for="newsletter">Subscribe to the newsletter</label>
    </div>
  </div>
</fieldset>
```

  </Step>
</Steps>

### HTML structure

<dl>
  <dt><code>&lt;fieldset class="fieldset"&gt;</code></dt>
  <dd>Native group for related fields. Use <code>&lt;legend&gt;</code> for the label and a following <code>&lt;p&gt;</code> for description.</dd>
  <dt><code>&lt;div role="group" class="fieldset"&gt;</code></dt>
  <dd>Structural group when <code>&lt;fieldset&gt;</code> is not appropriate. Add <code>aria-label</code> or <code>aria-labelledby</code>.</dd>
  <dt><code>&lt;div role="group" class="field"&gt;</code></dt>
  <dd>Single field wrapper. Add <code>data-orientation</code> when needed.</dd>
  <dt><code>&lt;label&gt;</code></dt>
  <dd>Label for the control. Use <code>for</code> when the control has an <code>id</code>.</dd>
  <dt><code>&lt;input&gt;</code>, <code>&lt;select&gt;</code>, <code>&lt;textarea&gt;</code></dt>
  <dd>Native form control. Put <code>aria-invalid="true"</code> on the invalid control, not only on the wrapper.</dd>
  <dt><code>&lt;section&gt;</code></dt>
  <dd>Optional content wrapper for label and description when the control sits beside text.</dd>
  <dt><code>&lt;p&gt;</code></dt>
  <dd>Helper text or error text. Use <code>role="alert"</code> for validation errors and connect it with <code>aria-describedby</code>.</dd>
</dl>

### Choice card

Wrap a `.field` inside a `<label>` to create selectable field cards. This works with radio, checkbox, and switch controls.

### Field group

Stack fields inside a group and use `.field-separator` to divide sections.

<div role="group" aria-label="Notification preferences" class="fieldset">
  <fieldset class="fieldset">
    <legend data-variant="label">Responses</legend>

        <input id="push-responses" type="checkbox" checked disabled />
        <label for="push-responses" class="font-normal">Push notifications</label>
      </div>
    </div>
  </fieldset>
  <div class="field-separator">
    <hr role="separator" />
  </div>
  <fieldset class="fieldset">
    <legend data-variant="label">Tasks</legend>
    <p>Get notified when tasks you've created have updates. <a href="#">Manage tasks</a></p>

        <label for="email-tasks" class="font-normal">Email notifications</label>
      </div>
    </div>
  </fieldset>
</div>
</Preview>

### Responsive layout

Use `data-orientation="responsive"` to stack by default and switch to horizontal in wider containers.

<Preview class="w-full max-w-4xl">
<form>
  <fieldset class="fieldset">
    <legend>Profile</legend>
    <p>Fill in your profile information.</p>
    <div class="field-separator">
      <hr role="separator" />
    </div>
    <div role="group" aria-label="Profile fields">
      <div role="group" class="field" data-orientation="responsive">
        <section>
          <label for="responsive-name">Name</label>
          <p id="responsive-name-description">Provide your full name for identification</p>
        </section>
        <input id="responsive-name" placeholder="Evil Rabbit" aria-describedby="responsive-name-description" required />
      </div>
      <div class="field-separator">
        <hr role="separator" />
      </div>
      <div role="group" class="field" data-orientation="responsive">
        <section>
          <label for="responsive-message">Message</label>
          <p id="responsive-message-description">You can write your message here. Keep it short, preferably under 100 characters.</p>
        </section>
        <textarea id="responsive-message" placeholder="Hello, world!" rows="4" aria-describedby="responsive-message-description" required class="min-h-[100px] resize-none sm:min-w-[300px]"></textarea>
      </div>
      <div class="field-separator">
        <hr role="separator" />
      </div>
      <div role="group" class="field" data-orientation="responsive">
        <button type="submit" class="btn">Submit</button>
        <button type="button" class="btn" data-variant="outline">Cancel</button>
      </div>
    </div>
  </fieldset>
</form>
</Preview>

### Validation and errors

Add `data-invalid` to `.field` and `aria-invalid="true"` to the invalid control.

<Preview class="w-full max-w-xs">
<div role="group" class="field" data-invalid>
  <label for="invalid-email">Email</label>
  <input id="invalid-email" type="email" value="wrong-email" aria-invalid="true" aria-describedby="invalid-email-error" />
  <p id="invalid-email-error" role="alert">Enter a valid email address.</p>
</div>
</Preview>

### RTL

Add `dir="rtl"` to the field, fieldset, or an ancestor.

<Preview class="w-full max-w-xs">
<fieldset class="fieldset" dir="rtl">
  <legend>الملف الشخصي</legend>
  <p>تظهر هذه المعلومات في حسابك.</p>
  <div role="group" aria-label="حقول الملف الشخصي">
    <div role="group" class="field">
      <label for="field-rtl-name">الاسم الكامل</label>
      <input id="field-rtl-name" type="text" placeholder="أرنب شرير" />
      <p>اكتب اسمك الأول والأخير.</p>
