|

|
||
|
||
> One command installs **36 themes × 20 canvas FX × 31 layouts × 15 full decks + presenter mode**. Every preview above is a live iframe of a real template file rendering inside the deck — no screenshots, no mock-ups.
|
||
|
||
## 🎤 Presenter Mode (new!)
|
||
|
||
Press `S` on any deck to pop open a dedicated presenter window with four
|
||
draggable, resizable **magnetic cards**: current slide, next slide preview,
|
||
speaker script (逐字稿), and timer. Two windows stay in sync via
|
||
`BroadcastChannel`.
|
||
|
||
|
||
|
||
**Why previews are pixel-perfect:** each card is an `<iframe>` that loads the
|
||
same deck HTML with a `?preview=N` query param. The runtime detects this and
|
||
renders only slide N with no chrome — so the preview uses the **same CSS,
|
||
theme, fonts and viewport** as the audience view. Colors and layout are
|
||
guaranteed identical.
|
||
|
||
**Smooth (no-reload) navigation:** on slide change, the presenter window
|
||
sends `postMessage({type:'preview-goto', idx:N})` to each iframe. The iframe
|
||
just toggles `.is-active` between slides — **no reload, no flicker**.
|
||
|
||
**Speaker script rules (3 golden):**
|
||
1. **Prompt signals, not lines to read** — bold the keywords, separate
|
||
transition sentences into their own paragraphs
|
||
2. **150–300 words per slide** — that's the ~2–3 min/page pace
|
||
3. **Write it like you speak** — conversational, not written prose
|
||
|
||
See [`references/presenter-mode.md`](references/presenter-mode.md) for the
|
||
full authoring guide, or copy the ready-made template at
|
||
`templates/full-decks/presenter-mode-reveal/` which ships with full 150-300
|
||
word speaker scripts on every slide.
|
||
|
||
## 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"
|
||
|
||
## What's in the box
|
||
|
||
| | Count | Where |
|
||
|---|---|---|
|
||
| 🎤 **Presenter mode** | **NEW** | `S` key / `?preview=N` |
|
||
| 🎨 **Themes** | **36** | `assets/themes/*.css` |
|
||
| 📑 **Full-deck templates** | **15** | `templates/full-decks/<name>/` |
|
||
| 🧩 **Single-page layouts** | **31** | `templates/single-page/*.html` |
|
||
| ✨ **CSS animations** | **27** | `assets/animations/animations.css` |
|
||
| 💥 **Canvas FX animations** | **20** | `assets/animations/fx/*.js` |
|
||
| 🖼️ **Showcase decks** | 4 | `templates/*-showcase.html` |
|
||
| 📸 **Verification screenshots** | 56 | `scripts/verify-output/` |
|
||
|
||
### 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 `<link>` 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).
|
||
|
||
|
||
|
||
### 15 Full-deck templates
|
||
|
||
Eight extracted from real-world decks, seven 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`,
|
||
**`presenter-mode-reveal`** 🎤 — complete talk template with full 150-300
|
||
word speaker scripts on every slide, designed around the `S` key presenter mode
|
||
|
||
Each is a self-contained folder with scoped `.tpl-<name>` 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.
|
||
|
||
|
||
|
||
*The big iframe is loading `templates/single-page/<name>.html` directly and cycling through all 31 layouts every 2.8 seconds.*
|
||
|
||
|
||
|
||
### 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 `<iframe>` per slide so each preview is a real, independent render.
|
||
- **Zero build.** Pure static HTML/CSS/JS. CDN only for webfonts, highlight.js
|
||
and chart.js (optional).
|
||
- **Senior-designer defaults.** Opinionated type scale, spacing rhythm,
|
||
gradients and card treatments — no "Corporate PowerPoint 2006" vibes.
|
||
- **Chinese + English first-class.** Noto Sans SC / Noto Serif SC pre-imported.
