Use the `loop` attribute to enable the looping of your slides.

```html
<div>
  <sd-carousel loop>
    <sd-carousel-item>
      <div class="slot slot--border slot--text h-16">Default slot 1</div>
    </sd-carousel-item>
    <sd-carousel-item>
      <div class="slot slot--border slot--text h-16">Default slot 2</div>
    </sd-carousel-item>
    <sd-carousel-item>
      <div class="slot slot--border slot--text h-16">Default slot 3</div>
    </sd-carousel-item>
  </sd-carousel>
</div>
```
