Chrome's developer team is pointing coding-agent users to Modern Web Guidance as a way to generate scroll-driven animations that are less brittle across screen sizes and browser environments. The project gives AI coding agents a searchable set of web-platform skills, including guidance for native CSS scroll animation patterns, fallbacks and accessibility constraints.

Chrome 115, Edge 115 and Safari 26 are listed as supported, while Firefox is listed as unsupported, so fallback behavior remains part of the implementation story.
