CSS animation adapter patterns for HyperFrames. Use when authoring CSS keyframes, animation-delay based timing, animation-fill-mode, animation-play-state, or CSS-only motion that HyperFrames must seek deterministically during preview and rendering.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CSS Animations for HyperFrames HyperFrames can seek CSS keyframe animations through its `css` runtime adapter. Use this for simple repeated motifs, background motion, shimmer, glow, masks, and non-sequenced decoration. For scene choreography, GSAP is usually clearer. CSS animations work best when the motion belongs to one element and has a fixed duration. ## Contract - Put the animated element in the DOM before runtime initialization finishes. - Give timed elements a `data-start` value so local animation time matches the clip. - Use finite `animation-duration` and `animation-iteration-count` because the negative-delay fallback cannot represent unbounded duration in environments without WAAPI-backed CSS animations. - Prefer `animation-fill-mode: both` so seeked states hold before and after active motion. - Avoid wall-clock JavaScript, hover-triggered state, and class toggles that depend on user events. The adapter discovers elements with computed `animation-name`, seeks their browser `Animation` handles when available, and falls back to pausing with negative `animation-delay`. ## Basic Pattern ```html <div id="pulse-ring" class="clip pulse-ring" data-start="0" …

How to install
mdr add anton-abyzov/vskill/css-animations@sha256:7ddb45c6e97b2f05The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
