SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Creating animated explainer visuals usually requires motion-graphics tools and JavaScript animation libraries. This Skill produces a complete, self-contained HTML page with looping CSS keyframe animations — pixel-art sprites, glitching display years, kinetic Japanese type, and a scrolling timeline ribbon — ready to be screen-recorded into a vertical video. ## Core Features & Use Cases - Pure CSS Animation: Builds at least three independent looping animations (bobbing sprite, glitch year, kinetic kana, scrolling tick ribbon) using only @keyframes, with no JavaScript. - Inline Pixel Art: Renders pixel-art mascots as inline SVG with shape-rendering: crispEdges or CSS box-shadow grids, so no external assets are needed. - Design System Integration: Reads the active DESIGN.md tokens to pick serif display, sans headline, and mono label fonts that match the project brand. - Use Case: Ask for a Nintendo history explainer and receive a 16:9 cream-stage frame showing a glitching "1889年", a bobbing Hanafuda card sprite, fading kanji, and a scrolling year-tick ribbon — one beat of an educational motion video. ## Quick Start Ask the AI to create a sprite animation introducing trivia about Nintendo's history with a pixel mascot, animated text, and a Hanafuda accent.

Frequently Asked Questions about sprite-animation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a pixel-art animation without JavaScript?▼

Use CSS @keyframes with the animation property set to infinite for looping motion. Pixel sprites can be drawn as inline SVG rectangles with shape-rendering: crispEdges, then animated with transform keyframes like a ±4px bob over 1.6 seconds.

How to make a glitch text effect with CSS only?▼

Duplicate the text in an absolutely positioned overlay span, color it with an accent, and animate its clip-path inset values with steps() timing. Brief visibility windows around 89-97% of the loop create the glitch flicker.

Can CSS animations be screen-recorded into a video?▼

Yes. A fixed-ratio stage such as 16:9 with looping infinite animations reads as a single frame of a motion video when screen-recorded. Keeping all animations on independent loop durations makes the recording feel continuously alive.

Does this animation approach require external image assets?▼

No. All sprites are built from inline SVG rectangles or CSS box-shadow pixel grids, and backgrounds use CSS gradients for paper grain. The output is a single HTML document with inline styles and no external files.

What are the limitations of pure CSS sprite animation?▼

CSS keyframes cannot react to user input, audio, or timeline scrubbing, and complex frame-by-frame sprite sheets are impractical. For interactive or long-form animation, a JavaScript canvas or video-editing workflow is more appropriate.
