# Loop Deck 11

> Image cards flip through a stacked deck, the front card leaving to reveal the next. 8 image slots, 10s seamless loop, 1:1.

## Install

<InstallCommand command="npx hyperframes add loop-deck-11" item="loop-deck-11" />

That writes one file: `compositions/loop-deck-11.html`.

## Add it to your video

It runs for 10 seconds at 1080×1080. Paste this into your composition:

```html index.html theme={null}
<div
  data-composition-id="loop-deck-11"
  data-composition-src="compositions/loop-deck-11.html"
  data-start="0"
  data-duration="10"
  data-track-index="1"
  data-width="1080"
  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.

## Variables

Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:

| Variable                  | Default                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                | Accepts                                           | What it does                                                                             |
