html-based slides

Create interactive, self-contained HTML slide decks with sidebar navigation, comment panel, zoom controls, inline editing, and present mode. Default brand is Shopee/Sea but supports custom brand presets. Use when the user says "做slides"、"create slides"、"创建幻灯片"、"做PPT"、"做汇报"、"bi-weekly"、"biweekly"、"双周汇报"、"quarterly review"、"product review"、"roadmap presentation"、"strategy deck"、"post-mortem slides", or any request to create a presentation deck.

Corporate Slides

Create zero-dependency, interactive HTML presentations that run in any browser. Every output is a single self-contained HTML file with built-in navigation, commenting, editing, and presentation capabilities.

Core Principles

1. Zero Dependencies — Single HTML file with inline CSS/JS. No npm, no build tools.
2. Interactive Chrome — Left sidebar navigation (bilingual-aware), right comment panel, zoom controls, inline text editing, present mode, EN/CN language switch — all built in by default.
3. Viewport Fitting (NON-NEGOTIABLE) — Every slide MUST fit exactly within 100vh. No scrolling within slides.
4. Brand-Configurable — Default brand is Shopee/Sea. User can select a different brand preset or define custom colors/fonts. The design token system makes this a single-point swap.
5. Content-Driven — Slides are built around data, comparisons, timelines, and action items — not filler graphics.
6. Bilingual by Default — Unless user specifies a single language, generate both EN and CN content for every text element with an EN/CN toggle in the toolbar. If user explicitly requests a single language, skip the toggle and generate monolingual content.

Phase 0: Detect Mode

• Mode A: New Presentation — Create from scratch. Go to Phase 1.
• Mode B: Enhancement — Modify an existing HTML slide deck. Read it first, understand its brand/style, then modify. When adding content, check density limits; split slides if overflow would occur.

---

Phase 1: Content Discovery

Ask ALL questions in a single call:

Question 1 — Purpose (header: "Purpose"): What is this presentation for? Options:

• Bi-weekly / periodic update
• Product review / feature walkthrough
• Roadmap / strategy deck
• Post-mortem / retrospective
• Quarterly business review
• Training / onboarding
• Other (describe)

Question 2 — Brand (header: "Brand"): Which brand preset? Options:

• Shopee / Sea (default — orange + navy)
• Custom (I'll provide colors/fonts)
• Neutral / Minimal (dark charcoal + blue accent, no logos)

Question 3 — Content (header: "Content"): Do you have content ready? Options:

• All content ready (paste text, metrics, etc.)
• Rough notes / bullet points
• Topic only — help me structure it

Question 4 — Length (header: "Length"): Approximately how many slides? Options: Short 5-8 / Medium 8-14 / Long 14+

Question 5 — Interactive Features (header: "Features"): Which interactive features to include? Options:

• Full (sidebar + comments + zoom + edit + present + language toggle) — recommended
• Light (sidebar + present only)
• Minimal (no chrome, static slides)

Language handling (NO question needed — apply automatically):

• If user has NOT specified a single language → generate bilingual (EN + CN) with language toggle. This is the default.
• If user explicitly says "English only", "只要中文", or similar → generate monolingual, no toggle.
• The language toggle is part of the toolbar chrome, not a separate question.

If user selected Custom brand, follow up with:

• Primary accent color (hex)
• Secondary / heading color (hex)
• Display font preference (or "your choice")
• Logo image file (or "no logo")

If user has content, ask them to share it. Then proceed to Phase 2.

Phase 2: Plan Slide Structure

Based on user content, plan the slide deck using available slide types and components.

Available Slide Types

Type	When to Use
Cover	First slide — title, date, team, optional logos
Section Divider	Transition between major topics — colored background, section number
Content	Main information slides — header bar + body components
Closing	Last slide — thank you, contact, next steps

Available Components (for Content Slides)

Read components.md for full HTML templates.

Component	Best For
Metrics Grid	KPI cards (3-column) with values and change indicators
Bi-weekly Table	Period-over-period comparison with insight cards
Feature Table	Feature comparisons, scope definitions, matrices
Two-Column Grid	Findings vs Actions, Pros vs Cons, Before vs After
Action List	Action items, scope items, decisions with owners
Timeline	Roadmap milestones, project phases
Status Badge	Inline status indicators (on-track, at-risk, done)
Screenshot Slot	Replaceable image placeholder for operational screenshots (dashed border when empty, auto-shows image when src set)

Content Density Limits Per Slide

Slide Type	Maximum Content
Cover	Title + subtitle + meta
Section Divider	Title + subtitle + section number
Content (text)	1 heading + 1 paragraph + 1 component
Content (table)	1 heading + 1 table (up to 12 rows)
Content (mixed)	1 heading + 2 smaller components
Closing	Title + subtitle + meta

Content exceeds limits? Split into multiple slides. Never cram, never scroll.

Present the slide plan to the user for confirmation before generating.

Phase 3: Generate Presentation

Brand Resolution

1. If Shopee/Sea (default): use the Shopee/Sea preset from design-tokens.md. MUST include BOTH base64-embedded Shopee and SeaMoney logos on cover, section dividers, content headers, and closing slides.
2. If Custom: swap --accent-primary, --accent-secondary, --color-navy, fonts, and logo. Keep all other structural tokens unchanged.
3. If Neutral: use the Neutral preset from design-tokens.md. No logos — use a text-only header.

HTML Architecture

text

<!DOCTYPE html>
<html lang="zh">
<head>
    <!-- Google Fonts (based on brand preset) -->
    <style>
        /* 1. CSS Custom Properties (from design-tokens.md — brand-resolved) */
        /* 2. Reset & Base Typography */
        /* 3. Viewport Fitting (MANDATORY — from viewport-chrome.md) */
        /* 4. Language Toggle (bilingual only — from viewport-chrome.md) */
        /* 5. Sidebar Navigation */
        /* 6. Progress Bar */
        /* 7. Comment Panel */
        /* 8. Zoom Controls */
        /* 9. Slide Type Styles (cover, section, content, closing) */
        /* 10. Component Styles */
        /* 11. Edit Mode */
        /* 12. Present Mode */
        /* 13. Responsive Breakpoints */
        /* 14. Embedded Logos (if applicable) */
    </style>
</head>
<body class="lang-cn">
    <!-- Chrome: sidebar + toggle (left), progress bar (top, slide area only), horizontal toolbar (top-right: lang→present→zoom→edit→comment), comment panel (right) -->
    <!-- SLIDES (each is a <section class="slide">) with lang-en/lang-cn spans -->
    <!-- JS: SlidePresentation class -->
</body>
</html>

Before generating, read ALL reference files:

• design-tokens.md — CSS custom properties, brand presets, typography
• slide-types.md — HTML templates for each slide type
• components.md — Reusable component HTML/CSS
• viewport-chrome.md — Interactive chrome + viewport rules
• js-controller.md — SlidePresentation JS class

Bilingual Content Rules (when generating EN + CN)

Every user-visible text element must contain both language spans:

html

<h2>
    <span class="lang-en">Architecture Overview</span>
    <span class="lang-cn">架构概览</span>
</h2>
<p>
    <span class="lang-en">Smart acts as a Package Registry.</span>
    <span class="lang-cn">Smart 作为 Package Registry。</span>
</p>

Rules:

1. Wrap each translatable text node in <span class="lang-en"> and <span class="lang-cn">
2. Technical terms, product names, and code snippets stay unchanged across both languages (e.g. "SKILL.md", "SuperAgent", "CLI", variable names)
3. data-title (CN) and data-title-en (EN) attributes on slides; data-group (CN) and data-group-en (EN) on group headers. Sidebar switches language along with body class.
4. The <html lang> attribute should be set to "zh" (CN is the default display language)
5. Body starts with class lang-cn — CN is shown first, user toggles to EN
6. For list items, wrap the text content inside each <li>, not the <li> itself
7. For table cells, wrap content inside each <td>/<th>, not the cell itself

CSS (included in viewport-chrome.md):

css

body.lang-en .lang-cn { display: none; }
body.lang-cn .lang-en { display: none; }

When monolingual: Skip all lang-en/lang-cn spans, write plain text, omit the language toggle button from the toolbar, and omit the language CSS/JS.

Key Requirements

1. Single self-contained HTML file — all CSS/JS inline
2. Every slide must have data-title (CN), data-title-en (EN), data-group (CN), and data-group-en (EN) attributes for bilingual sidebar. Monolingual slides only need data-title and data-group.
3. Every slide must include a footer with page numbers (populated by JS)
4. All sizes must use clamp(min, preferred, max) — never fixed px/rem
5. Logos: Shopee/Sea — BOTH .shopee and .seamoney logos MUST appear, embedded via CSS content: url(data:...). Custom brand — embed user-provided logo(s). Neutral — no logos, text-only headers.
6. Include prefers-reduced-motion support
7. Clear /* === SECTION NAME === */ comment blocks throughout CSS
8. Bilingual presentations must include the EN/CN language switch in the toolbar and all lang-en/lang-cn CSS (see viewport-chrome.md). Sidebar nav must also be bilingual-aware.

Phase 4: Delivery

1. Save to work/slides/ with a descriptive filename
2. Open using open [filename].html to launch in browser
3. Summarize — Tell the user:
   • File location, slide count, brand preset used
   • Navigation: Arrow keys, Space, scroll/swipe, sidebar click
   • Top-right toolbar (horizontal, left to right): Language switch → Present → Zoom → Edit → Comment
   • Language: Click "EN" or "CN" segment in the switch to change language; sidebar nav follows. Press L to toggle.
   • Present: Press F5 or click ▶ — fullscreen, hides all chrome
   • Zoom: +/- buttons (70%–150%)
   • Edit: Press E — click any text to edit, undo/redo in toolbar
   • Comment panel: Press C — per-slide notes saved to localStorage, Copy All exports as Markdown
   • Sidebar: Click ☰ at sidebar right edge to collapse/expand
