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

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

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

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
14 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), 6 scenario scaffolds (pitch-deck, product-launch, tech-sharing, weekly-report, xhs-post 3:4, course-module)
31 layouts (templates/single-page/*.html) with realistic demo data
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/S/O
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.

Do not start writing slides until you understand three things. Either ask the user directly, or — if they already handed you rich content — propose a tasteful default and confirm.

Content & audience. What's the deck about, how many slides, who's watching (engineers / execs / 小红书读者 / 学生 / VC)?
Style / theme. Which of the 36 themes fits? If unsure, recommend 2-3 candidates based on tone:
- Business / investor pitch → pitch-deck-vc, corporate-clean, swiss-grid
- Tech sharing / engineering → tokyo-night, dracula, catppuccin-mocha, terminal-green, blueprint
- 小红书图文 → xiaohongshu-white, soft-pastel, rainbow-gradient, magazine-bold
- Academic / report → academic-paper, editorial-serif, minimal-white
- Edgy / cyber / launch → cyberpunk-neon, vaporwave, y2k-chrome, neo-brutalism
Starting point. One of the 14 full-deck templates, or scratch? Point to the closest templates/full-decks/<name>/ and ask if it fits. If the user's content suggests something obvious (e.g. "我要做产品发布会" → product-launch), propose it confidently instead of asking blindly.

A good opening message looks like:

我可以给你做这份 PPT！先确认三件事：

大致内容 / 页数 / 观众是谁？

风格偏好？我建议从这 3 个主题里选一个：tokyo-night（技术分享默认好看）、xiaohongshu-white（小红书风）、corporate-clean（正式汇报）。

要不要用我现成的 tech-sharing 全 deck 模板打底？

Only after those are clear, scaffold the deck and start writing.

Quick start

Scaffold a new deck. From the repo root:

./scripts/new-deck.sh my-talk
open examples/my-talk/index.html

Pick a theme. Open the deck and press T to cycle. Or hard-code it:
```
<link rel="stylesheet" id="theme-link" href="../assets/themes/aurora.css">
```
Catalog in references/themes.md.
Pick layouts. Copy <section class="slide">...</section> blocks out of files in templates/single-page/ into your deck. Replace the demo data. Catalog in references/layouts.md.
Add animations. Put data-anim="fade-up" (or class="anim-fade-up") on any element. On <ul>/grids, use anim-stagger-list for sequenced reveals. For canvas FX, use <div data-fx="knowledge-graph">...</div> and include <script src="../assets/animations/fx-runtime.js"></script>. Catalog in references/animations.md.
Use a full-deck template. Copy templates/full-decks/<name>/ into examples/my-talk/ as a starting point. Each folder is self-contained with scoped CSS. Catalog in references/full-decks.md and gallery at templates/full-decks-index.html.

Render to PNG.

./scripts/render.sh templates/theme-showcase.html       # one shot
./scripts/render.sh examples/my-talk/index.html 12      # 12 slides

Authoring rules (important)

Always start from a template. Don't author slides from scratch — copy the closest layout from templates/single-page/ first, then replace content.
Use tokens, not literal colors. Every color, radius, shadow should come from CSS variables defined in assets/base.css and overridden by a theme. Good: color: var(--text-1). Bad: color: #111.
Don't invent new layout files. Prefer composing existing ones. Only add a new templates/single-page/*.html if none of the 30 fit.
Respect chrome slots. .deck-header, .deck-footer, .slide-number and the progress bar are provided by assets/base.css + runtime.js.
Keyboard-first. Always include <script src="../assets/runtime.js"></script> so the deck supports ← → / T / A / F / S / O / hash deep-links.
One .slide per logical page. runtime.js makes .slide.is-active visible; all others are hidden.
Supply notes. Wrap speaker notes in <div class="notes">…</div> inside each slide. Press S to open the overlay.
NEVER put presenter-only text on the slide itself. Descriptive text like "这一页展示了……" or "Speaker: 这里可以补充……" or small explanatory captions aimed at the presenter MUST go inside <div class="notes">, NOT as visible <p> / <span> elements on the slide. The .notes class is display:none by default — it only appears in the S overlay. Slides should contain ONLY audience-facing content (titles, bullet points, data, charts, images).

Rendering to PNG

scripts/render.sh wraps headless Chrome at /Applications/Google Chrome.app/Contents/MacOS/Google Chrome. For multi-slide capture, runtime.js exposes #/N deep-links, and render.sh iterates 1..N.

./scripts/render.sh templates/single-page/kpi-grid.html        # single page
./scripts/render.sh examples/demo-deck/index.html 8 out-dir    # 8 slides, custom dir
