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.

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)
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/O, S (presenter mode: magnetic-card popup with CURRENT / NEXT / SCRIPT / TIMER cards), N (notes drawer), R (reset timer in presenter)
FX runtime (assets/animations/fx-runtime.js) — auto-inits [data-fx] on slide enter, cleans up on leave

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 for the full authoring guide including the 3 rules of speaker script writing:
不是讲稿，是提示信号 — 加粗核心词 + 过渡句独立成段
每页 150–300 字 — 2–3 分钟/页的节奏
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.
Before you author anything — ALWAYS ask or recommend
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).

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.
