Taoteching Deck Template

Tao Te Ching Deck Template Skill

This skill is the HTML / CSS / JS source of truth for the taoteching-deck squad. It documents the canonical 10-page deck skeleton, every reusable class, and every animation keyframe. Copy from here verbatim — do not re-derive.

This skill is dedicated to the Tao Te Ching deck format. Other classical-text projects should fork the squad rather than extend this skill.

Architecture at a Glance

• One file. All CSS in a single <style> block, all JS in a single inline <script>. No <link>, no <script src>, no @import, no remote URL of any kind.
• Engine. ~60 lines of vanilla JS implements horizontal slide transitions via transform: translateX(-cur*100vw), plus keyboard / wheel (800ms throttle) / touch (50px swipe) / dot navigation. No reveal.js, no impress.js.
• 10-page rhythm. Cover (P1), concept overview (P2), original text (P3), five paragraph-by-paragraph analyses (P4–P8), key line (P9), chapter summary (P10).
• CJK font stack only. System 楷体 (KaiTi) + 宋体 (SimSun) fallback chain. No web fonts.
• Three-colour palette. Gold #f5c97a for highlights, red #c53d43 for paragraph numbers and history (史) labels, green #2d5a3d for modern-case borders.
• Background strategy. Default = gradient placeholder + TODO comment. Optional = base64 image inlined per slide (file balloons to 4-5 MB).

Comment language note. This skill's prose is in English. The HTML / CSS samples below preserve the Chinese sample copy and CSS comments verbatim because the deliverable is consumed by Chinese-speaking authors and readers. When operators write the actual deck, those Chinese strings (slide titles, chapter text, TODO image hints) stay Chinese.

CSS Variables (canonical block)

:root {
  --ink:   #1a1a2e;
  --ink2:  #12121f;
  --paper: #f0e6d3;
  --dim:   #b8a88a;
  --red:   #c53d43;
  --gold:  #d4a574;
  --green: #2d5a3d;
  --kai:   "楷体","KaiTi","STKaiti","华文楷体",serif;
  --song:  "宋体","SimSun","STSong",serif;
}

The brighter highlight gold used inside <strong> and the key-line <em> is the literal hex #f5c97a (do not promote to a variable; it is intentionally distinct from --gold).

Engine

Layout primitive

*, *::before, *::after { margin:0; padding:0; box-sizing:border-box; }
html, body {
  height:100%;
  overflow:hidden;
  font-family: var(--song);
  background: var(--ink);
  color: var(--paper);
  -webkit-user-select: none;
  user-select: none;
}
.deck { display:flex; height:100vh; transition: transform 0.6s cubic-bezier(0.4,0,0.2,1); }
.slide {
  flex: 0 0 100vw;
  height: 100vh;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  position: relative;
  padding: 60px;
  overflow: hidden;
}

Background halo (subtle ambient glow on every slide)

.slide::before {
  content:''; position:absolute; top:-30%; right:-20%;
  width:60%; height:60%;
  background: radial-gradient(ellipse, rgba(45,90,61,0.1) 0%, transparent 70%);
  border-radius:50%; filter:blur(60px); pointer-events:none;
}
.slide::after {
  content:''; position:absolute; bottom:-20%; left:-15%;
  width:50%; height:50%;
  background: radial-gradient(ellipse, rgba(197,61,67,0.06) 0%, transparent 70%);
  border-radius:50%; filter:blur(80px); pointer-events:none;
}

When a slide carries its own opaque mask ::before (cover, original-text, paragraph, key-line, summary), redeclare the mask on the slide-class selector to override the ambient halo (see per-slide CSS below).

Slide-entry stagger (declarative, no JS)

.slide .a    { opacity:0; transform: translateY(25px); transition: opacity 0.6s ease, transform 0.6s ease; }
.slide.on .a { opacity:1; transform: translateY(0); }
.slide.on .d1 { transition-delay: .10s; }
.slide.on .d2 { transition-delay: .25s; }
.slide.on .d3 { transition-delay: .40s; }
.slide.on .d4 { transition-delay: .55s; }
.slide.on .d5 { transition-delay: .70s; }
.slide.on .d6 { transition-delay: .85s; }

In HTML, write class="a d2" to give an element the entry animation with the second delay step. No JS needed.

Navigation chrome

.arr {
  position:fixed; top:50%; transform:translateY(-50%); z-index:100;
  width:46px; height:46px; display:flex; align-items:center; justify-content:center;
  border:1px solid rgba(240,230,211,0.15); border-radius:50%;
  background:rgba(26,26,46,0.6); backdrop-filter:blur(8px);
  cursor:pointer; transition:all .3s; color:var(--dim); font-size:18px;
}
.arr:hover { border-color:var(--gold); color:var(--gold); background:rgba(212,165,116,0.1); }
.arr-l { left:20px; } .arr-r { right:20px; }
.arr.hide { opacity:0; pointer-events:none; }

.dots {
  position:fixed; bottom:26px; left:50%; transform:translateX(-50%); z-index:100;
  display:flex; gap:10px; align-items:center;
}
.dot {
  width:8px; height:8px; border-radius:50%;
  background:rgba(240,230,211,0.15); cursor:pointer; transition:all .3s;
}
.dot.on { background:var(--gold); width:24px; border-radius:4px; }

.pn {
  position:fixed; top:26px; right:34px; z-index:100;
  font-family:var(--kai); font-size:14px; color:var(--dim);
  opacity:.5; letter-spacing:2px;
}

JS engine (verbatim — copy into the deck)

<script>
!function(){
  var cur=0,dk=document.getElementById('dk'),ss=dk.querySelectorAll('.slide'),
      tot=ss.length,bl=document.getElementById('bl'),br=document.getElementById('br'),
      pn=document.getElementById('pn'),ds=document.getElementById('ds'),busy=0;

  for(var i=0;i<tot;i++){
    var d=document.createElement('div');
    d.className='dot'+(i?'':' on');
    d.setAttribute('data-i',i);
    d.onclick=function(){goTo(+this.getAttribute('data-i'))};
    ds.appendChild(d);
  }

  function goTo(n){
    if(n<0||n>=tot||n===cur||busy)return;
    busy=1;
    ss[cur].classList.remove('on');
    cur=n;
    dk.style.transform='translateX(-'+cur*100+'vw)';
    ui();
    setTimeout(function(){ss[cur].classList.add('on')},100);
    setTimeout(function(){busy=0},600);
  }

  function go(d){goTo(cur+d)}
  window.go=go;

  function ui(){
    bl.classList.toggle('hide',cur===0);
    br.classList.toggle('hide',cur===tot-1);
    pn.textContent=(cur+1)+' / '+tot;
    var dd=ds.querySelectorAll('.dot');
    for(var i=0;i<dd.length;i++)dd[i].classList.toggle('on',i===cur);
  }

  document.addEventListener('keydown',function(e){
    if(e.key==='ArrowRight'||e.key==='ArrowDown'||e.key===' '){e.preventDefault();go(1)}
    else if(e.key==='ArrowLeft'||e.key==='ArrowUp'){e.preventDefault();go(-1)}
  });

  var sx=0,sy=0;
  dk.addEventListener('touchstart',function(e){sx=e.touches[0].clientX;sy=e.touches[0].clientY},{passive:true});
  dk.addEventListener('touchend',function(e){
    var dx=e.changedTouches[0].clientX-sx,dy=e.changedTouches[0].clientY-sy;
    if(Math.abs(dx)>Math.abs(dy)&&Math.abs(dx)>50)go(dx<0?1:-1);
  },{passive:true});

  var wt=null;
  // Wheel: full-document capture is intentional — the deck is a fullscreen kiosk, page scroll is never desired.
  document.addEventListener('wheel',function(e){
    e.preventDefault();
    if(wt)return;
    wt=setTimeout(function(){wt=null},800);
    go((Math.abs(e.deltaX)>Math.abs(e.deltaY)?e.deltaX:e.deltaY)>0?1:-1);
  },{passive:false});

  ss[0].classList.add('on');
  ui();
}();
</script>

The slide count tot is derived from document.querySelectorAll('.slide') at runtime — adding or removing a slide requires no JS edit.

Animation Library (verbatim keyframes)

These class+keyframe pairs power every animated SVG element on every slide. Reuse them; do not invent new keyframes per page.

.an-pulse   { animation: kPulse 3s ease-in-out infinite; transform-origin:center; }
.an-pulse-d { animation-delay: .8s; }
@keyframes kPulse { 0%,100%{ opacity:.3; transform:scale(1); } 50%{ opacity:.7; transform:scale(1.08); } }

.an-glow    { animation: kGlow 4s ease-in-out infinite; }
.an-glow-d  { animation-delay: 1.2s; }
@keyframes kGlow  { 0%,100%{ opacity:.4; } 50%{ opacity:1; } }

.an-bob     { animation: kBob 3.5s ease-in-out infinite; }
.an-b1{animation-delay:0s} .an-b2{animation-delay:.6s}
.an-b3{animation-delay:1.2s} .an-b4{animation-delay:1.8s}
@keyframes kBob   { 0%,100%{ transform:translateY(0); } 50%{ transform:translateY(-10px); } }

.an-ring    { animation: kRing 4s ease-in-out infinite; }
.an-r1{animation-delay:0s} .an-r2{animation-delay:.5s} .an-r3{animation-delay:1s}
@keyframes kRing  { 0%,100%{ opacity:.15; stroke-dashoffset:0; } 50%{ opacity:.5; stroke-dashoffset:12; } }

.an-drift   { animation: kDrift 5s ease-in-out infinite; }
.an-drift-r { animation: kDrift 5s ease-in-out infinite reverse; }
@keyframes kDrift { 0%,100%{ transform:translate(0,0); } 50%{ transform:translate(6px,-6px); } }

.an-spin    { animation: kSpin 24s linear infinite; transform-origin: 100px 100px; }
.an-spin-r  { animation: kSpin 18s linear infinite reverse; transform-origin: 100px 100px; }
@keyframes kSpin  { from{ transform:rotate(0); } to{ transform:rotate(360deg); } }

.an-fade    { animation: kFade 5s ease-in-out infinite; }
.an-f1{animation-delay:0s} .an-f2{animation-delay:1.5s} .an-f3{animation-delay:3s}
@keyframes kFade  { 0%,100%{ opacity:.2; } 50%{ opacity:.85; } }

Note (.an-spin rotation centre): transform-origin: 100px 100px assumes the SVG uses viewBox="0 0 200 200" (the canonical 180×180 concept-diagram size in this template). If you author an SVG with a different viewBox, override transform-origin inline on the rotating <g> so the rotation pivots around the visual centre.

SVG Concept Diagrams (180×180, one per analysis page)

These five patterns covered the 25-chapter reference. Reuse them for analogous concepts in any chapter; remix labels and animation classes freely.

Pattern A — Concentric circles + central glyph (use for substance-of-the-Tao concepts; e.g., 道之体)

<svg class="pa-svg" viewBox="0 0 200 200">
  <g class="an-spin">
    <circle cx="100" cy="100" r="78" fill="none" stroke="rgba(212,165,116,0.15)" stroke-width="1" stroke-dasharray="3,8"/>
    <circle cx="100" cy="100" r="60" fill="none" stroke="rgba(45,90,61,0.25)"  stroke-width="1" stroke-dasharray="2,10"/>
  </g>
  <g class="an-spin-r">
    <circle cx="100" cy="100" r="42" fill="none" stroke="rgba(197,61,67,0.3)" stroke-width="1" stroke-dasharray="4,6"/>

</svg>

Pattern B — Question mark + named opposites (use for naming-paradox concepts; e.g., 道之名)

<svg class="pa-svg" viewBox="0 0 200 200">
  <circle cx="100" cy="100" r="58" fill="none" stroke="rgba(240,230,211,0.2)" stroke-width="1" stroke-dasharray="3,5" class="an-ring an-r1"/>

</svg>

Pattern C — Four-direction cycle (use for cyclic concepts; e.g., 道之运 — 大→逝→远→反)

<svg class="pa-svg" viewBox="0 0 200 200">
  <circle cx="100" cy="100" r="60" fill="none" stroke="rgba(212,165,116,0.25)" stroke-width="1" stroke-dasharray="4,6" class="an-spin"/>

  <circle cx="100" cy="100" r="6" fill="rgba(212,165,116,0.5)" class="an-pulse"/>
</svg>

<svg class="pa-svg" viewBox="0 0 200 200">
  <circle cx="100" cy="100" r="86" fill="none" stroke="rgba(212,165,116,0.45)" stroke-width="1.5" class="an-glow"/>

Assembly Outline

For most chapters, do not assemble from scratch. Copy templates/skeleton.html, then fill in only the chapter-specific text and SVG content. The assembly outline below is for reference (or for understanding what's in the skeleton); the skeleton is the source of truth — see the "Placeholder Cheatsheet" at the end of this skill for the full {{TOKEN}} set the operator must replace.

The assembled deck is built by stitching the canonical sections from this skill into one HTML file. This outline shows where each section lands; it is not a runnable file by itself — fill in each placeholder by copying from the corresponding section earlier in this skill.

A complete worked Chapter 25 deck (around 41 KB with gradient placeholders) is what every snippet in this skill was extracted from — operators authoring a new chapter can use those snippets as the worked example, then swap the chapter number, title, original text, paragraph commentary, case studies, and SVG label content while keeping every class name and CSS rule intact.

Background Strategy Reference

When inlining base64, encode each image as data:image/jpeg;base64,... and place inside the slide-class CSS rule, replacing the gradient. Always pair with mask opacity 0.85-0.92 so the busy image does not wash out the text.

Recommended imagery menu by slide (the Chinese phrases are the search prompts an operator should use against any image source — they describe the look, not the page label):

UTF-8 Safety (repeat warning)

The deck is heavy CJK content. Never generate it with bash heredoc (cat << EOF), echo redirection containing Chinese characters, or any shell-string concatenation that crosses an encoding boundary. Always write the file via create / edit tools or Python:

with open("taoteching-33.html", "w", encoding="utf-8") as f:
    f.write(html_content)

A single corrupted multi-byte sequence breaks a glyph silently and the page looks fine in your editor but renders garbled in the browser.

Placeholder Cheatsheet

templates/skeleton.html ships with double-brace {{TOKEN}} placeholders for every chapter-specific slot. The operator must replace every one before delivery; running grep '{{' taoteching-{N}.html after editing should return zero matches.

Header / cover (P1)

Concept overview (P2)

Original text (P3)

Per-paragraph analysis (P4 – P8) — same eight tokens repeated for each of P4, P5, P6, P7, P8 (prefixed P4_ … P8_)

(PN stands for P4, P5, P6, P7, or P8 — replicate the cluster five times.)

Key line (P9)

Summary (P10)

Verification: after editing the deck, run grep '{{' taoteching-{N}.html. The expected count is zero. If any token survives, an authoring slot was missed.
