## Add it to your video

It runs for 8 seconds at 1920×1080. Paste this into your composition:

```html index.html
<div
  data-composition-id="liquid-glass-notification"
  data-composition-src="compositions/liquid-glass-notification.html"
  data-start="0"
  data-duration="8"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>
```

Move it in time with `data-start`. Put it on a different timeline row with
`data-track-index`. See [data attributes](/concepts/data-attributes.md) for the rest.

{/* hf:generated-footer */}

Tagged `html-in-canvas` `liquid-glass-html-in-canvas` `webgpu`.
