Minimal Deck Template

Every deck follows this structure — assets/base.css + one theme file + runtime.js:

CSS Animations

Add class to any element. Use --delay CSS variable for staggering.

<h1 class="animate-on-enter rise-in">Title</h1>
<p class="animate-on-enter fade-up" style="--delay:0.2s">Subtitle</p>
<img class="animate-on-enter zoom-pop" style="--delay:0.4s" src="..." />

Canvas FX Animations

Add data-fx attribute to trigger cinematic canvas effects on slide enter:

<!-- Particle effects -->
<section class="slide" data-layout="cover" data-fx="particle-burst">
  <div class="slide-content">
    <h1>Big Launch</h1>
  </div>
</section>

<!-- Celebration -->
<section class="slide" data-layout="thanks" data-fx="confetti-cannon">
  <div class="slide-content"><h1>Thank You!</h1></div>
</section>

<!-- Tech / Data -->
<section class="slide" data-layout="arch-diagram" data-fx="knowledge-graph">

<section class="slide" data-fx="constellation">…</section>
<section class="slide" data-fx="galaxy-swirl">…</section>
<section class="slide" data-fx="orbit-ring">…</section>

<!-- Text FX -->
<section class="slide" data-fx="typewriter-multi">…</section>
<section class="slide" data-fx="word-cascade">…</section>
<section class="slide" data-fx="letter-explode">…</section>
<section class="slide" data-fx="counter-explosion">…</section>

<section class="slide" data-fx="firework">…</section>
<section class="slide" data-fx="chain-react">…</section>
<section class="slide" data-fx="magnetic-field">…</section>

fx-runtime.js auto-initialises these on slide enter — no extra JS needed.

Speaker Notes

Add notes inside .slide-notes — revealed by pressing S:

<section class="slide" data-layout="bullets">
  <div class="slide-content">
    <h2>Architecture Overview</h2>
    <ul class="stagger-list">
      <li>Service A handles ingestion</li>
      <li>Service B handles processing</li>
    </ul>
  </div>
  <!-- Hidden from audience, shown in presenter overlay -->
  <aside class="slide-notes">
    Mention: Service A uses Kafka. Budget 3 min here. 
    Demo link: internal.company.com/demo
  </aside>
</section>

Deep Linking & URL Navigation

Link directly to a slide by appending #N or ?slide=N:

<!-- Link to slide 5 in a shared deck -->
<a href="my-deck/index.html#5">Jump to Architecture slide</a>

<!-- From JS -->
window.location.hash = '3';

Keyboard Controls

Key	Action
`← → Space PgUp PgDn`	Navigate slides
`Home / End`	First / last slide
`F`	Fullscreen
`S`	Speaker notes overlay
`O`	Slide overview grid
`T`	Cycle through themes
`A`	Demo animation on current slide

Troubleshooting

Animations not firing on slide enter

Ensure fx-runtime.js is loaded after runtime.js
Check data-fx value matches a name in assets/animations/fx/*.js
Canvas FX requires a visible <canvas> — fx-runtime.js injects one automatically if absent

Theme not applying

Only one theme <link> should be active at a time
Theme file must be loaded after base.css
Scoped deck templates use .tpl-<name> class on <body> — add it when embedding

Fonts not loading (offline)

fonts.css loads Noto Sans SC / Noto Serif SC from Google Fonts CDN
For offline use, download fonts and update @font-face paths in assets/fonts.css

3:4 ratio slides look stretched

Add aspect-ratio: 3 / 4 and constrain max-width on .slide (see XHS example above)
Default slides are 16:9 widescreen

Code blocks not highlighted

Include highlight.js from CDN: <script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/highlight.min.js"></script>
Call hljs.highlightAll() after DOM load

Chart layouts blank

chart-bar, chart-line, chart-pie, chart-radar layouts expect Chart.js
Include: <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
