# Neon Border

> Two arcs of light travel the edge of a rounded panel and snap corner to corner, trailing a soft three-layer bloom. A lower third for a name and role.

<video className="w-full aspect-video rounded-xl object-cover bg-zinc-100 dark:bg-zinc-800" src="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/lt-neon-border.mp4" poster="https://static.heygen.ai/hyperframes-oss/docs/images/catalog/blocks/lt-neon-border.png" autoPlay muted loop playsInline />

## Install

```bash Terminal theme={null}
npx hyperframes add lt-neon-border
```

That writes one file: `compositions/lt-neon-border.html`.

## Add it to your video

It runs for 4.8 seconds at 1920×1080. Paste this into your composition:

```html index.html theme={null}
<div
  data-composition-id="lt-neon-border"
  data-composition-src="compositions/lt-neon-border.html"
  data-start="0"
  data-duration="4.8"
  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) for the rest.
