amp-anim

A runtime-managed animated image, typically a GIF.

Required Script <script async custom-element="amp-anim" src="https://cdn.ampproject.org/v0/amp-anim-0.1.js"></script>
Supported Layouts fill, fixed, fixed-height, flex-item, intrinsic, nodisplay, responsive
Examples Annotated code example for amp-anim

Behavior

The amp-anim component is almost identical to the amp-img element, but allows the AMP runtime to reduce CPU usage when the animation is off-screen. Like other elements, it supports an optional placeholder child, to display while the src file is loading:

<amp-anim width="400" height="300" src="my-gif.gif">
  <amp-img placeholder width="400" height="300" src="my-gif-screencap.jpg">
  </amp-img>
</amp-anim>

In the future, additional functionality, such as animation playback control, could be added.

Attributes

src Similar to the src attribute on the img tag. For emails, the URL must be https.
srcset Same as srcset attribute on the img tag.
alt A string of alternate text, similar to the alt attribute on img.
attribution A string that indicates the attribution of the image. For example, attribution="CC courtesy of Cats on Flicker".
height and width An explicit size of the image, which is used by the AMP runtime to determine the aspect ratio without fetching the image.
common attributes This element includes common attributes extended to AMP components.

Styling

amp-img can be styled directly via CSS properties. Setting a grey background placeholder for example could be achieved via:

amp-anim {
  background-color: grey;
}

Validation

See amp-anim rules in the AMP validator specification.
