motion-frames
A single-frame motion-design composition with looping CSS animations — rotating type ring, animated globe, ticking timer, parallax labels. Renders as a hero video poster you can hand straight to HyperFrames or any keyframe-based exporter. Use when the brief asks for "motion design", "animated hero", "loop", "video poster", "title card", or pairs Open Claude Design with HyperFrames for a kinetic export.
Why this skill is useful
Provides specific CSS animation patterns and design composition techniques that enhance the AI's ability to create motion graphics.

What this skill does
Motion Frames Skill Produce a single full-bleed motion composition. Inline CSS animations only — the page is the loop. Treat it as a poster frame that an exporter (HyperFrames, Lottie, etc.) can capture into a video. Workflow 1. Read the active DESIGN.md (injected above). Motion lives or dies on typography contrast — pick the most expressive serif / display token in the DS for the headline; the body / mono token labels everything else. 2. Compose the canvas as a 16:9 hero with these layers, back to front: Stage — full-bleed <main>. Off-white or DS-canvas background, very subtle dotted grid texture (CSS background, radial-gradient dots at 22–32px intervals). Concentric rings — 2–3 SVG circles radiating from a focal point. Ultra-thin strokes (0.5–1px) in DS-foreground at low opacity. These rotate at different speeds (60s, 90s, 180s). Focal mark — a wireframe globe, a stylized object, or a typographic monogram drawn as inline SVG. ~28% of the canvas wide. Ring labels — short words / phonetic tokens placed around one of the rings (e.g. "Hola · Bonjour · 你好 · नमस्ते"). They co-rotate with the ring, with <text> paths counter-rotated so the words stay upright. Headline — bottom-left or center-bottom. Display serif, italic accent on one word. Add a subtle letterSpacing + opacity reveal animation (@keyframes type-in). Frame chrome — corner stamps (top-left lab tag, top-right brand or issue number) and a thin baseline rule. Static. 3. Animate with @keyframes only — no JS: rotate-slow, rotate-med, rotate-fast for rings. globe-spin for the focal mark. pulse for the focal dot, ~2s, easing. marquee-fade to reveal headline once on load. 4. Write a single HTML document: <!doctype html> through </html>, CSS inline. All motion uses CSS — no scripts, so HyperFrames or any frame-grabber can capture it deterministically. data-od-id on stage, focal, ring, headline, chrome. 5. Self-check: The composition still reads as a poster with motion paused at frame 0. …
