# iframe embeds

Embed a fixed LittleDemo player with URL parameters.

An iframe is the safest default for a fixed demo.

```html
<iframe
  src="https://littledemo.com/embed/demo_abc123"
  width="100%"
  height="400"
  frameborder="0"
  allow="autoplay; fullscreen"
  allowfullscreen
></iframe>
```

## Parameters

```html
<iframe
  src="https://littledemo.com/embed/demo_abc123?autoplay=true&loop=true&controls=false"
  width="100%"
  height="400"
  frameborder="0"
  allow="autoplay; fullscreen"
></iframe>
```

See [embed parameters](/reference/embed-parameters) for the full list.

## Sizing

Use a responsive wrapper when the host CMS lets you add CSS:

```html
<div style="position:relative;width:100%;aspect-ratio:16/9">
  <iframe
    src="https://littledemo.com/embed/demo_abc123"
    style="position:absolute;inset:0;width:100%;height:100%;border:0"
    allow="autoplay; fullscreen"
    allowfullscreen
  ></iframe>
</div>
```

## When not to use iframe

Use the JavaScript SDK if you need to create players dynamically, listen for playback events, or generate demos from page context.
