## Install (one command)
```bash
npx skills add https://github.com/lewislulu/html-ppt-skill
```
That registers the skill with your agent runtime. After install, any agent
that supports AgentSkills can author presentations by asking things like:
> "做一份 8 页的技术分享 slides，用 cyberpunk 主题"
> "turn this outline into a pitch deck"
> "做一个小红书图文，9 张，白底柔和风"

### 36 Themes
`minimal-white`, `editorial-serif`, `soft-pastel`, `sharp-mono`, `arctic-cool`,
`sunset-warm`, `catppuccin-latte`, `catppuccin-mocha`, `dracula`, `tokyo-night`,
`nord`, `solarized-light`, `gruvbox-dark`, `rose-pine`, `neo-brutalism`,
`glassmorphism`, `bauhaus`, `swiss-grid`, `terminal-green`, `xiaohongshu-white`,
`rainbow-gradient`, `aurora`, `blueprint`, `memphis-pop`, `cyberpunk-neon`,
`y2k-chrome`, `retro-tv`, `japanese-minimal`, `vaporwave`, `midcentury`,
`corporate-clean`, `academic-paper`, `news-broadcast`, `pitch-deck-vc`,
`magazine-bold`, `engineering-whiteprint`.
Each is a pure CSS-tokens file — swap one `` to reskin the entire deck.
Browse them all in `templates/theme-showcase.html` (each slide rendered in an
isolated iframe so theme ≠ theme is visually guaranteed).
### 14 Full-deck templates
Eight extracted from real-world decks, six generic scenario scaffolds:
**Extracted looks**
- `xhs-white-editorial` — 小红书白底杂志风
- `graphify-dark-graph` — 暗底 + 力导向知识图谱
- `knowledge-arch-blueprint` — 蓝图 / 架构图风
- `hermes-cyber-terminal` — 终端 cyberpunk
- `obsidian-claude-gradient` — 紫色渐变卡
- `testing-safety-alert` — 红 / 琥珀警示风
- `xhs-pastel-card` — 柔和马卡龙图文
- `dir-key-nav-minimal` — 方向键极简
**Scenario decks**
- `pitch-deck`, `product-launch`, `tech-sharing`, `weekly-report`,
`xhs-post` (9-slide 3:4), `course-module`
Each is a self-contained folder with scoped `.tpl-` CSS so multiple
decks can be previewed side-by-side without collisions. Browse the full
gallery in `templates/full-decks-index.html`.
### 31 Single-page layouts
cover · toc · section-divider · bullets · two-column · three-column ·
big-quote · stat-highlight · kpi-grid · table · code · diff · terminal ·
flow-diagram · timeline · roadmap · mindmap · comparison · pros-cons ·
todo-checklist · gantt · image-hero · image-grid · chart-bar · chart-line ·
chart-pie · chart-radar · arch-diagram · process-steps · cta · thanks
Every layout ships with realistic demo data so you can drop it into a deck
and immediately see it render.
### 27 CSS animations + 20 Canvas FX
**CSS (lightweight)** — directional fades, `rise-in`, `zoom-pop`, `blur-in`,
`glitch-in`, `typewriter`, `neon-glow`, `shimmer-sweep`, `gradient-flow`,
`stagger-list`, `counter-up`, `path-draw`, `morph-shape`, `parallax-tilt`,
`card-flip-3d`, `cube-rotate-3d`, `page-turn-3d`, `perspective-zoom`,
`marquee-scroll`, `kenburns`, `ripple-reveal`, `spotlight`, …
**Canvas FX (cinematic)** — `particle-burst`, `confetti-cannon`, `firework`,
`starfield`, `matrix-rain`, `knowledge-graph` (force-directed physics),
`neural-net` (signal pulses), `constellation`, `orbit-ring`, `galaxy-swirl`,
`word-cascade`, `letter-explode`, `chain-react`, `magnetic-field`,
`data-stream`, `gradient-blob`, `sparkle-trail`, `shockwave`,
`typewriter-multi`, `counter-explosion`. Each is a real hand-rolled canvas
module auto-initialised on slide enter via `fx-runtime.js`.

## Philosophy
- **Token-driven design system.** All color, radius, shadow, font decisions
live in `assets/base.css` + the current theme file. Change one variable,
the whole deck reflows tastefully.
- **Iframe isolation for previews.** Theme / layout / full-deck showcases all
use `
