sprite-animation

A pixel / sprite-style animated explainer slide — full-bleed cream stage, bold display year, animated pixel-art mascot (e.g. Hanafuda card, mushroom, or 8-bit console), kinetic Japanese display type, ticking timeline ribbon. Reads like a single frame of an educational motion video — looping CSS keyframes, no JS, ready to be screen-recorded into a vertical video. Use when the brief asks for a "sprite animation", "pixel-art video", "8-bit explainer", "history of X explainer", "kinetic typography history", "Nintendo-style", "精灵图动画", "像素动画", or "复古动画".

Sprite Animation Skill

Produce a single animated frame of an educational explainer — the kind you might screen-record into a vertical video. Pixel-art mascots, big year display, looping CSS animations, kinetic Japanese / English display type.

Workflow

Read the active DESIGN.md (injected above). Pick the loudest serif token for the year, a sturdy sans for headlines, and a mono token for timeline / index labels.
Pick the topic from the brief (e.g. "Nintendo · 1889 — Hanafuda"). You always need: a year, a one-line headline, an animated subject (a pixel sprite — character, object, or icon), and a short caption.
Stage — full-bleed cream / off-white background (#f5efe2) with a subtle paper grain. Keep margins generous; this is one beat of a video.
Top bar — small mono row:
- Left: title slug ("名次の/番組" or "EP. 01 / NINTENDO")
- Right: progress dots ("01 / 12") and a "REC" stamp
Subject animations — at least three independent looping animations on the page:
- Big year: the headline year (e.g. "1889年") fills the lower-left, in a serif display weight. It has a subtle vertical glitch / scanline animation (clip-path keyframes), and a 1-frame "pop" every loop.
- Pixel sprite card: a 96×128 pixel-art card or character (use an inline SVG with crisp shape-rendering: crispEdges rectangles, or a box-shadow pixel grid). Subtle bobbing animation (±4px, 1.6s).
- Kinetic kana: 1–2 Japanese / kanji characters that fade-and-slide in sync with the bob (e.g. "花" — hana — flower).
- Tick ribbon: bottom of the stage, a tape/ribbon with year ticks (1889 · 1907 · 1949 · 1977 · 1985 · 2006 · 2017) sliding left at a slow constant speed.
Caption block — small mono caption explaining the trivia: "Nintendo started as a Hanafuda playing-card maker in Kyoto, 1889. Mario didn't show up for another ninety-six years."
Write a single HTML document:
- <!doctype html> through </html>, CSS inline, no external JS.
- All animations use @keyframes + animation: ... infinite.
- Stage uses a fixed canvas ratio (e.g. 16:9 letterboxed) so the loop reads as a single frame from a video.
- data-od-id on stage, year, sprite, caption, and tick ribbon.
Self-check:
- The page is one cohesive scene, not a collage. The eye lands on the year first, then the sprite, then the caption.
- At least 3 independent looping animations are visible.
- The color palette is restrained (cream + a single accent red + ink).
- No external assets — all sprites are inline SVG or CSS.
