|A CSS Animations adapter skill for HyperFrames, the open-source HTML-to-video rendering framework by HeyGen. Enables AI coding agents to use CSS animations and keyframes within HyperFrames video compositions.
Overview
The css-animations skill is a HyperFrames adapter that teaches AI agents how to write CSS keyframe animation patterns compatible with HyperFrames video rendering. Standard CSS animations run on wall-clock time, making them non-deterministic during frame capture. This skill provides patterns that let HyperFrames discover, pause, and seek CSS animations frame-by-frame.
Key Features
- CSS @keyframes patterns that HyperFrames can automatically discover and control during frame-accurate rendering
- Seekable animation techniques where HyperFrames pauses and steps through CSS animations at each captured frame
- Works alongside other adapters (GSAP, Anime.js, Lottie, Three.js, WAAPI) for mixed-runtime compositions
- Integrates with the HyperFrames dev-loop: init, preview, lint, and render to MP4
- Deterministic rendering where identical inputs always produce identical video output
Who is this for?
- Developers who prefer pure CSS animations over JavaScript libraries when building HyperFrames compositions
- AI agent users who need CSS keyframe animations to render correctly in the frame capture pipeline
- Teams wanting lightweight, dependency-free animations within automated video pipelines
