Explainer https://drafts.csswg.org/css-image-animation-1/explainer Specification https://drafts.csswg.org/css-image-animation-1 Summary Introduces a new CSS property and pseudo-class to control and detect animated images like GIFs and APNGs. 1. image-animation: Can be set to "normal", "running", or "paused" to control image animation playback. 2. :animated-image: A pseudo-class to determine whether an image is animated. Blink component Blink>CSS Web Feature ID Missing feature Motivation Currently, user agents autoplay animated images (eg, GIF, WebP, PNG) by default. This behavior can be violate accessibility standards regarding pausing and stopping content. Site authors currently lack mechanisms to control this playback. The only existing methods are browser-specific global settings, which are inconsistent and lack the features needed for developers to build accessible, per-image playback interfaces.

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
