# html-ppt — HTML PPT Studio

Author professional HTML presentations as static files. One theme file = one
look. One layout file = one page type. One animation class = one entry effect.
All pages share a token-based design system in `assets/base.css`.

## Install

```bash
npx skills add https://github.com/lewislulu/html-ppt-skill
```

One command, no build. Pure static HTML/CSS/JS with only CDN webfonts.

No network on the target machine? Point the CLI at a local copy
(`npx skills add ./html-ppt-skill`), or just copy this folder into your agent's
skills directory — `~/.claude/skills/html-ppt/` for Claude Code. Decks render
offline; only the webfonts fall back to the system stack. See
[README.md](README.md#offline--manual-install).

## What the skill gives you

- **36 themes** (`assets/themes/*.css`) — minimal-white, editorial-serif, soft-pastel, sharp-mono, arctic-cool, sunset-warm, catppuccin-latte/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
- **15 full-deck templates** (`templates/full-decks/<name>/`) — complete multi-slide decks with scoped `.tpl-<name>` CSS. 8 extracted from real-world decks (xhs-white-editorial, graphify-dark-graph, knowledge-arch-blueprint, hermes-cyber-terminal, obsidian-claude-gradient, testing-safety-alert, xhs-pastel-card, dir-key-nav-minimal), 7 scenario scaffolds (pitch-deck, product-launch, tech-sharing, weekly-report, xhs-post 3:4, course-module, **presenter-mode-reveal** — 演讲者模式专用)
- **36 layouts** (`templates/single-page/*.html`) with realistic demo data, including **5 real-image layouts** (single / full-bleed / image+text / gallery / before-after)
- **27 CSS animations** (`assets/animations/animations.css`) via `data-anim`
- **20 canvas FX animations** (`assets/animations/fx/*.js`) via `data-fx` — particle-burst, confetti-cannon, firework, starfield, matrix-rain, knowledge-graph (force-directed), neural-net (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
- **Keyboard runtime** (`assets/runtime.js`) — arrows, T (theme), A (anim), F/O, **S (presenter mode: magnetic-card popup with CURRENT / NEXT / SCRIPT / TIMER cards)**, N (notes drawer), R (reset timer in presenter)
- **Touch navigation** — swipe left/right to change slides on phones and tablets
- **FX runtime** (`assets/animations/fx-runtime.js`) — auto-inits `[data-fx]` on slide enter, cleans up on leave
- **Showcase decks** for themes / layouts / animations / full-decks gallery
- **Headless Chrome render script** for PNG export

## When to use

Use when the user asks for any kind of slide-based output or wants to turn
text/notes into a presentable deck. Prefer this over building from scratch.

### 🎤 Presenter Mode (演讲者模式 + 逐字稿)

If the user mentions any of: **演讲 / 分享 / 讲稿 / 逐字稿 / speaker notes / presenter view / 演讲者视图 / 提词器**, or says things like "我要去给团队讲 xxx", "要做一场技术分享", "怕讲不流畅", "想要一份带逐字稿的 PPT" — **use the `presenter-mode-reveal` full-deck template** and write 150–300 words of 逐字稿 in each slide's `<aside class="notes">`.

See [references/presenter-mode.md](references/presenter-mode.md) for the full authoring guide including the 3 rules of speaker script writing:
1. **不是讲稿,是提示信号** — 加粗核心词 + 过渡句独立成段
2. **每页 150–300 字** — 2–3 分钟/页的节奏
3. **用口语,不用书面语** — "因此"→"所以","该方案"→"这个方案"

All full-deck templates support the S key presenter mode (it's built into `runtime.js`). **S opens a new popup window with 4 magnetic cards**:
- 🔵 **CURRENT** — pixel-perfect iframe preview of the current slide
- 🟣 **NEXT** — pixel-perfect iframe preview of the next slide
- 🟠 **SPEAKER SCRIPT** — large-font 逐字稿 (scrollable)
- 🟢 **TIMER** — elapsed time + slide counter + prev/next/reset buttons

Each card is **draggable by its header** and **resizable by the bottom-right corner handle**. Card positions/sizes persist to `localStorage` per deck. A "Reset layout" button restores the default arrangement.

**Why the previews are pixel-perfect**: each preview is an `<iframe>` that loads the actual deck HTML with a `?preview=N` query param; `runtime.js` 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 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**. The two windows also stay in sync via `BroadcastChannel`.

Only `presenter-mode-reveal` is designed from the ground up around the feature with proper example 逐字稿 on every slide.

Keyboard in presenter window: `← →` navigate (syncs audience) · `R` reset timer · `Esc` close popup.
Keyboard in audience window: `S` open presenter · `T` cycle theme · `← →` navigate (syncs presenter) · `F` fullscreen · `O` overview.
