# Divider

Hairline rule. Solid or dashed; horizontal or vertical.

Preview: https://design.freecodecamp.org/playground#divider

## Add to your project

Use React and TypeScript. Required packages: `react@>=18 <20`. No freeCodeCamp package is needed.

Copy the files below to the indicated paths, relative to your project root. If you change the layout, update relative imports too.

Import the CSS once from your application entry. For an entry in src/:

```ts
import './ui/theme/tokens.css';
import './ui/theme/base.css';
import './ui/divider/divider.css';
```

The theme is shared: reuse it if already installed. Fonts use /fonts/ URLs on your host. Download the font files listed in https://design.freecodecamp.org/registry/starter.md or change those URLs in your copied tokens.css.

## Example

```tsx
import { Divider } from './ui/divider/Divider';

export function Example() {
  return (
    <div style={{ display: 'grid', gap: 16, width: '100%' }}>
      <Divider />
      <Divider variant='dashed' />
      <div style={{ display: 'flex', alignItems: 'center', height: 48 }}>
        <span>Before</span>
        <Divider orientation='vertical' />
        <span>After</span>
      </div>
    </div>
  );
}
```

## Interaction guidance

Review https://www.w3.org/WAI/ARIA/apg/patterns/ and test keyboard operation in your project.
