The Focus extension adds a CSS class to focused nodes. By default it adds `.has-focus`, but you can change that.

Note that it’s only a class, the styling is totally up to you. The usage example below has some CSS for that class.

## Installation
```bash
# with npm
npm install @tiptap/extension-focus

# with Yarn
yarn add @tiptap/extension-focus
```

## Settings

### className
The class that is applied to the focused element.

Default: `'has-focus'`

```js
Focus.configure({
  className: 'focus',
})
```

### mode
Apply the class to `'all'`, the `'shallowest'` or the `'deepest'` node.

Default: `'all'`

```js
Focus.configure({
  mode: 'deepest',
})
```
