### WYSIWYG Content

```html
<div class="content">
  <!-- start WYSIWYG contents -->
  <h1>Heading</h1>
  <p>Paragraph</p>

  <ul>
    <li>Item 1</li>
    <li>Item 2</li>
  </ul>
  <!-- end WYSIWYG contents -->
</div>
```

To provide default stylings for commonly generated WYSIWYG contents, use the `.content` class.
