HTML 簡報進階技巧（reveal.js）

使用時機：使用者想讓 HTML 簡報更生動、更好講、更適合現場互動，或問「有什麼特效或技巧可以加」。簡報本體的製作流程（版型、圖片、QA、轉 PPTX）在 html-slide-deck；本 skill 只管加在其上的效果。加完效果一律回頭跑 html-slide-deck 的 qa-screenshots.mjs。

固定規則：開始前先讀本 skill 目錄下的 references/fixed-rules.md，全程遵守（加效果也不得刪頁）。

使用原則（先讀）

只放在 4～5 個關鍵時刻：封面、章節轉折、核心概念圖、收尾。其他頁保持乾淨。
離線優先：所有函式庫從 npm 取得後內嵌進 HTML，不引用 CDN。影片檔例外，放在 HTML 旁邊，不轉 base64。
尊重減少動態效果：系統開了「減少動態效果」時，一律退回淡入淡出（見第 5 節）。
在實際播放的電腦上彩排：3D 和粒子在舊筆電或外接投影時可能卡頓。
每次加完都重跑驗收：逐頁截圖時關閉轉場，確認沒有溢出，最終狀態正確。

先問使用者：聽眾是誰、現場有沒有網路、播放電腦的等級、想要「穩重」還是「驚豔」。醫療或學術聽眾預設偏穩重，只用第 1、2 級。

1. 內建功能（零成本，優先使用）

逐步出現（Fragments）

<ul>
  <li class="fragment">第一點</li>
  <li class="fragment fade-up">第二點</li>
  <li class="fragment highlight-current-blue">目前講到這點</li>
</ul>
<div class="fragment" data-fragment-index="2">指定順序</div>

適合：條列、決策樹一步一步揭曉、比較表逐欄出現。

Auto-Animate（相鄰兩頁自動補間）

<section data-auto-animate>
  <div data-id="box" style="width:200px">Lv2</div>
</section>
<section data-auto-animate data-auto-animate-duration="0.8">
  <div data-id="box" style="width:900px">Lv2 Cloudflare Pages</div>
</section>

相同文字或相同 src 會自動配對；data-id 可手動指定配對。
可以動畫的屬性：位置、字級、顏色、背景、padding、margin。
適合：總覽圖放大成單項頁、流程圖某一步展開、prompt 變成結果。

轉場（每頁可不同）

<section data-transition="zoom">章節頁</section>
<section data-transition="convex-in fade-out" data-transition-speed="slow">…</section>

樣式：none、fade、slide、convex、concave、zoom；背景用 data-background-transition。建議全場 fade＋transitionSpeed:'fast'，只有章節頁用 zoom（每頁都 slide 看久會累，也讓換段落失去標記）。完整程式碼與快捷鍵見 repo docs/TECHNIQUES.md。

版面輔助 class

r-fit-text：文字自動放到最大，適合一句話頁。
r-stretch：圖片或影片填滿剩餘高度。
r-stack：多個元素疊在同一位置，搭配 fragment 依序替換。

手機捲動模式（Scroll view，5.0 起）

網址加 ?view=scroll，或設定 view: 'scroll'。
scrollActivationWidth 控制手機是否自動切換；設 null 或 0 則關閉。
用途：部署後在封面放 QR，聽眾用手機跟著看、會後帶走。

點圖放大（Lightbox，5.2 起；html-slide-deck 範本已是 5.2）

<img src="shot.png" data-preview-image>
<video data-preview-video="demo.mp4"></video>

需要 reveal.js 5.2 以上；從 5.1 升級後要重跑驗收。

背景影片

<section data-background-video="demo.mp4" data-background-video-muted data-background-video-loop></section>

適合：現場 demo 的預錄備案。

講者要知道的快捷鍵

S 講者備註、Esc／O 總覽、F 全螢幕、B 或 . 黑屏、G 跳頁、網址加 ?print-pdf 匯出 PDF。

2. 小型外掛（可內嵌）

外掛	用途	注意
elapsed-time-bar（tkrkt）	底部時間進度條，和頁數進度條對照，看出講快還是講慢	設 `allottedTime`（毫秒），可暫停、重設
Chalkboard（rajgoel）	`C` 在投影片上畫、`B` 開黑板、`D` 下載畫記	需要 Font Awesome（自有授權），要一起內嵌才能離線；`B` 與 reveal 內建黑屏鍵衝突，要改鍵
Spotlight（denniskniep）	滑鼠變聚光燈，其他區域變暗	講解截圖細節時很有效
reveal.js-menu	側邊目錄快速跳頁	Q&A 時找頁面方便

內嵌方式：把外掛的 JS 與 CSS 讀進建置腳本，直接寫進 <script> 與 <style>，並加入 plugins: [...]。套件名稱與版本以各外掛 repo 為準，不要猜 npm 名稱；抓不到就自己寫（計時條約 20 行）。

不建議：需要伺服器的投票或問答外掛（Poll、Seminar、Questions）。現場互動改用使用者自己的課堂互動工具，並準備口頭提問作為沒網路時的備案。

3. 3D 與炫技動畫

CSS 3D（純 CSS，離線）

卡片翻面：

.flip { perspective: 1000px; }
.flip .inner { transition: transform .8s; transform-style: preserve-3d; position: relative; }
.flip.visible .inner { transform: rotateY(180deg); }
.flip .front, .flip .back { backface-visibility: hidden; position: absolute; inset: 0; }
.flip .back { transform: rotateY(180deg); }

<div class="flip fragment custom"><div class="inner"><div class="front">工具名稱</div><div class="back">教學用法</div></div></div>

.reveal .fragment.custom { opacity: 1; visibility: inherit; }   /* 沒有 custom 時，卡片在點擊前是隱形的，正面看不到 */
.flip.visible .inner { transform: rotateY(180deg); }

（fragment 顯示時加上 visible class → 翻面；一組卡片想一次翻，把 fragment custom 放在容器上，卡片用 transition-delay 錯開。）

立體階梯：父層 perspective: 1200px，每一階 transform: rotateX(20deg) translateZ(n*40px)，每階加 fragment 依序升起。

卡片牆飛入：每張卡片的起始狀態是 transform: translateZ(-800px) rotateY(40deg); opacity: 0，出現時回到 0；用 transition-delay 錯開。

GSAP（2025 年起完全免費，含 SplitText、MorphSVG）

從 npm 安裝 gsap，內嵌 dist/gsap.min.js（約 70 KB）；需要外掛時一起內嵌，例如 dist/SplitText.min.js。
在切換到該頁時才播放：

Reveal.on('slidechanged', (e) => {
  if (e.currentSlide.id === 'cover') {
    gsap.from('#cover h1 .char', { y: 40, opacity: 0, stagger: 0.04, duration: 0.6 });
  }
});

數字跳動：

const o = { v: 0 };
gsap.to(o, { v: 13, duration: 1.2, onUpdate: () => (el.textContent = Math.round(o.v)) });

適合：封面標題逐字浮現、收尾數字計數、流程圖 SVG 形狀變形。

Three.js（真 3D，檔案大）

新版只提供 ES module，要用 esbuild 把 three 和自己的程式打包成一個 IIFE 檔，再內嵌。
只在需要的頁面執行 render loop，離開就停：

Reveal.on('slidechanged', (e) => (running = e.currentSlide.id === 'cover'));

適合：封面粒子星空、旋轉地球、可轉動的解剖模型。
會讓 HTML 增加數百 KB（esbuild 打包只用到的模組約 530 KB），務必在播放電腦上測試幀率。
可直接用的封面粒子模組：repo examples/three-particles-entry.js（掛在 Reveal.getSlideBackground(0)，只在封面跑）。

impress.js（整份變成 3D 畫布，類似 Prezi）

每頁用 data-x、data-y、data-z、data-rotate-y、data-scale 定位，頁與頁之間鏡頭飛行。
要換掉整個框架，只在使用者明確想要全場鏡頭飛行時才用。一般用 reveal.js 在單頁內模擬即可。

View Transitions API

適合多頁式網站的頁面間轉場；reveal.js 單頁簡報通常不需要。

4. 最有說服力的互動：頁面裡放能用的東西

講「AI 30 秒做出測驗」時，同一頁直接放一個能作答的小測驗（純 JS，離線可用），現場請聽眾點。
講工具時放 QR code（用 qrcode 套件在建置時產生 SVG 內嵌），並用解碼驗證網址正確。
示範結果比描述結果更有說服力，這類頁面優先於任何特效。

5. 減少動態效果與效能保護

@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after { animation: none !important; transition-duration: .01ms !important; }
}

const REDUCE = matchMedia('(prefers-reduced-motion: reduce)').matches;
// STATIC：QA 截圖（Playwright）與 ?print-pdf 時關掉所有動畫，截到的才是最終狀態
const STATIC = navigator.webdriver || location.search.indexOf('print-pdf') >= 0;
if (STATIC) document.documentElement.classList.add('static');
Reveal.initialize({ transition: REDUCE ? 'fade' : 'slide', autoAnimateDuration: STATIC ? 0 : 0.9, pdfSeparateFragments: false /* ... */ });
if (REDUCE || STATIC) { /* 不啟動 GSAP 與 Three.js、計時條，直接顯示最終狀態 */ }

html.static .flip .inner, html.static .reveal .fragment { transition: none !important; }

prefers-reduced-motion 的 CSS 只作用在自己加的效果（.flip、GSAP 目標、fragment），不要用全域 * 把 reveal 換頁也壓掉。

6. 建議配置（依風格）

風格	使用
穩重（醫學、學術）	Fragments、Auto-Animate、章節 zoom、時間進度條、點圖放大、頁內互動
中間	再加 CSS 3D 階梯或卡片翻面、GSAP 封面與收尾
驚豔（發表會、開幕）	再加 Three.js 封面、卡片牆飛入、Spotlight

7. 驗收清單

逐頁截圖（先 Reveal.configure({ transition: 'none' })），沒有溢出
有 fragment 的頁面：?print-pdf 匯出時所有內容都出現
拔網路後重開，所有動畫、圖片、QR 正常
開啟「減少動態效果」後，簡報仍可完整閱讀
在實際播放的電腦上跑過一次，3D 頁面沒有卡頓
HTML 檔案大小可接受（一般 < 5 MB）
向使用者說明：加了哪些效果、在哪幾頁、怎麼關掉

與 html-slide-deck 的接點

Fragment 頁在 render-slides.mjs 轉講義時只會截到最終狀態（腳本已關閉轉場）；要每個 fragment 各一張就先把該頁拆成多頁。
內嵌 GSAP／外掛時，插入位置要在 reveal.js 之後、Reveal.initialize 之前；找最後一個 </body>（notes.js 原始碼裡也有一個）。
加了 elapsed-time-bar 之類的外掛後，qa-screenshots.mjs 的 errors 若出現外掛的 console error 要先修，再看版面。

# HTML 簡報進階技巧（reveal.js）

使用時機：使用者想讓 HTML 簡報更生動、更好講、更適合現場互動，或問「有什麼特效或技巧可以加」。簡報本體的製作流程（版型、圖片、QA、轉 PPTX）在 `html-slide-deck`；本 skill 只管加在其上的效果。加完效果一律回頭跑 `html-slide-deck` 的 `qa-screenshots.mjs`。

**固定規則**：開始前先讀本 skill 目錄下的 `references/fixed-rules.md`，全程遵守（加效果也不得刪頁）。

## 使用原則（先讀）

1. **只放在 4～5 個關鍵時刻**：封面、章節轉折、核心概念圖、收尾。其他頁保持乾淨。
2. **離線優先**：所有函式庫從 npm 取得後內嵌進 HTML，不引用 CDN。影片檔例外，放在 HTML 旁邊，不轉 base64。
3. **尊重減少動態效果**：系統開了「減少動態效果」時，一律退回淡入淡出（見第 5 節）。
4. **在實際播放的電腦上彩排**：3D 和粒子在舊筆電或外接投影時可能卡頓。
5. **每次加完都重跑驗收**：逐頁截圖時關閉轉場，確認沒有溢出，最終狀態正確。

Overview

HTML 簡報進階技巧（reveal.js）

使用原則（先讀）

1. 內建功能（零成本，優先使用）

逐步出現（Fragments）

Auto-Animate（相鄰兩頁自動補間）

轉場（每頁可不同）

版面輔助 class

手機捲動模式（Scroll view，5.0 起）

點圖放大（Lightbox，5.2 起；html-slide-deck 範本已是 5.2）

背景影片

講者要知道的快捷鍵

2. 小型外掛（可內嵌）

3. 3D 與炫技動畫

CSS 3D（純 CSS，離線）

GSAP（2025 年起完全免費，含 SplitText、MorphSVG）

Three.js（真 3D，檔案大）

impress.js（整份變成 3D 畫布，類似 Prezi）

View Transitions API

4. 最有說服力的互動：頁面裡放能用的東西

5. 減少動態效果與效能保護

6. 建議配置（依風格）

7. 驗收清單

與 html-slide-deck 的接點
