Create Presentation Skill

Purpose

Transform Jupyter notebooks into beautiful presentation-mode experiences using embedded HTML and JavaScript within markdown cells. Leverages EDS blocks for visual appeal while preventing code execution by users.

When to Use

• Creating presentation notebooks
• Building interactive demos without executable code
• Converting educational notebooks to presentation format
• Creating showcases, tutorials, or product demos
• Building slide-like experiences with EDS blocks
• Updating existing notebooks to presentation mode
• Applying inline HTML styling for beautiful, consistent appearance

Key Concepts

Presentation Mode vs Interactive Mode vs Educational Mode vs Navigation Mode

Interactive Notebooks (e.g., test.ipynb):

• Users can run JavaScript code cells
• Code cells have "Run" buttons
• For developers and testing

Educational Notebooks (e.g., tutorial.ipynb):

• Runnable code cells for learning
• Can use auto-wrapping in notebook mode (pure markdown)
• 60% markdown, 40% code
• For teaching and explaining
• See jupyter-educational-notebook skill

Presentation Notebooks (e.g., demo.ipynb):

• No executable code cells
• All interactivity via inline scripts in markdown
• Can use auto-wrapping (notebook mode) OR manual HTML (all modes)
• For end users, clients, presentations
• Beautiful visual layouts with EDS blocks

Navigation Notebooks (e.g., docs-navigation.ipynb):

• No executable code cells (pure navigation)
• 100% markdown with action cards
• Multi-paradigm navigation (role, task, workflow, category)
• For complex documentation systems (20+ documents)
• Progressive disclosure with part summaries
• See template: docs/for-ai/templates/ipynb/navigation-template.ipynb

Core Approach

1. All content in markdown cells - No code cells with executable JavaScript
2. Inline scripts in markdown - Use <script> tags within markdown for interactivity
3. EDS blocks via HTML - Embed block HTML directly in markdown
4. Conversion of existing code cells - Transform to informative markdown text
5. Choose styling approach:
   • Auto-wrapping (pure markdown) - When displayed in notebook mode
   • Manual HTML (inline styles) - When displayed in other modes or needing custom styling

Available EDS Blocks

See resources/blocks-reference.md for complete details on all blocks.

Visual Layout Blocks:

• accordion - Collapsible sections
• cards - Card grid layouts
• tabs - Tabbed content
• grid - Flexible grid layouts
• hero - Hero banners
• table - Data tables

Content Blocks:

• quote - Pull quotes
• columns - Multi-column layouts
• modal - Dialog overlays
• video - Embedded videos

Interactive Blocks:

• code-expander - Expandable code snippets
• counter - Animated counters
• floating-alert - Dismissible alerts

Quick Start

Creating a New Presentation

Use /create-presentation command with:
- Topic or title
- Key sections/topics
- Desired blocks (accordion, cards, tabs, etc.)

Example:

/create-presentation "Product Demo" with sections: Features, Benefits, Pricing
Use cards for features, accordion for benefits, table for pricing

Converting Existing Notebook

Use /create-presentation with path to existing .ipynb file
All code cells will be converted to informative markdown

Example:

/create-presentation convert education.ipynb
Keep structure but make it presentation-only

Structure Pattern

Metadata Setup

Every presentation notebook should have:

{
  "metadata": {
    "title": "Presentation Title",
    "description": "Brief description",
    "author": "Author Name",
    "creation-date": "{{TODAY'S DATE IN YYYY-MM-DD FORMAT}}",
    "version": "1.0",
    "last-modified": "{{TODAY'S DATE IN YYYY-MM-DD FORMAT}}",
    "category": "presentation",
    "repo": "https://github.com/username/repo",
    "manual-path": "docs/for-ai/your-documentation.md"
  }
}

⚠️ CRITICAL - Version and Date Management:

• ALWAYS update both version AND last-modified whenever you make ANY change to an .ipynb file
• Version increments:
  • Major changes (new slides, restructuring): 1.0 → 2.0
  • Minor changes (new content, edits): 1.0 → 1.1
  • Patch changes (typo fixes): 1.0 → 1.0.1
• Last-modified: Update to current date (YYYY-MM-DD) on every edit
• Creation-date: Never change after initial creation

Key Fields:

• title - Main presentation title (required)
• description - One-line summary (optional)
• author - Author name (optional)
• creation-date - Initial creation date in YYYY-MM-DD format (required, never change)
• version - Version tracking (required, increment on every edit)
• last-modified - Last modification date in YYYY-MM-DD format (required, update on every edit)
• category - Content category, e.g., "presentation" (optional)
• repo - Repository URL for linking .md files (optional)
• manual-path - Path to documentation for "Read the Manual" button (optional)
  • REQUIRED for button: Button only appears if manual-path is provided
  • With repo and plain .md: Creates GitHub link {repo}/blob/main/{manual-path}
  • Absolute path (/...): Used as-is
  • Relative path: Made absolute from root
  • Full URL: Used as-is
  • No default: If omitted, button will not appear

Cell Structure

Important: Do NOT automatically include a Table of Contents. The presentation template does not include a TOC by default. Only add navigation if explicitly requested by the user.

Typical structure:

Title Cell (Markdown):

# 🎯 Presentation Title

**Subtitle or tagline**

---

## Overview

Brief introduction to the presentation

Content Cells (Markdown with Embedded Blocks):

## Section Title

<div class="accordion block">
  <div>
    <div>Feature 1</div>
    <div>Description of feature 1 with details...</div>
  </div>
  <div>
    <div>Feature 2</div>
    <div>Description of feature 2 with details...</div>
  </div>
</div>

<script type="module">
  // Initialize block
  const block = document.querySelector('.accordion.block');
  const module = await import('/blocks/accordion/accordion.js');
  await module.default(block);
</script>

Navigation Cell (Markdown):

---

## 📋 Table of Contents

- [Section 1](#section-1)
- [Section 2](#section-2)
- [Conclusion](#conclusion)

Block Usage Patterns

Accordion Block (Collapsible Sections)

Best For: FAQs, feature lists, detailed explanations

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

<h2 style="color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;">Section Title</h2>

<div class="accordion block">
  <div>
    <div>Question or Title</div>
    <div>Answer or detailed content here...</div>
  </div>
</div>

<script type="module">
  const block = document.querySelector('.accordion.block');
  const module = await import('/blocks/accordion/accordion.js');
  await module.default(block);
</script>

</div>

Cards Block (Grid Layout)

Best For: Features, team members, product showcase

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

<h2 style="color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;">Section Title</h2>

<div class="cards block">
  <div>
    <div><strong>📊 Card Title</strong></div>
    <div>Card content with description...</div>
  </div>
  <div>
    <div><strong>🚀 Another Card</strong></div>
    <div>More content here...</div>
  </div>
</div>

<script type="module">
  const block = document.querySelector('.cards.block');
  const module = await import('/blocks/cards/cards.js');
  await module.default(block);
</script>

</div>

Tabs Block (Tabbed Content)

Best For: Organizing related information, code examples, comparisons

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

<h2 style="color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;">Section Title</h2>

<div class="tabs block">
  <div>
    <div>Tab 1</div>
    <div>Content for tab 1...</div>
  </div>
  <div>
    <div>Tab 2</div>
    <div>Content for tab 2...</div>
  </div>
</div>

<script type="module">
  const block = document.querySelector('.tabs.block');
  const module = await import('/blocks/tabs/tabs.js');
  await module.default(block);
</script>

</div>

See resources/blocks-reference.md for all block patterns.

Visual Consistency Standards

CRITICAL: All presentations must follow these exact styling standards for consistency.

Typography Standards

• H1 (Hero Title): font-size: 48px; font-weight: 800
• H2 (Major Sections): color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;
  • H2 emoji size: 32px
• H3 (Subsections): color: #0d47a1; font-size: 26px; font-weight: 700; margin-bottom: 20px;
  • H3 emoji size: 28px
  • Use flexbox pattern: display: flex; align-items: center; gap: 12px;
• Body text: font-size: 16px; line-height: 1.8; color: #212121;
• List item emojis: 20px
• TOC/Navigation links: font-size: 18px; font-weight: 500
• IMPORTANT: Use HTML headings with explicit styling, NOT markdown syntax (##, ###)
• Markdown headings render with default grey colors - always use HTML

Background Standards

• Standard gradient: background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%);
• All content divs MUST include: color: #212121; to prevent text fading
• Margin: margin: 0 0; (no vertical gaps that expose dark ipynb-viewer background)
• Border radius: border-radius: 12px;
• Padding: padding: 32px;

Border Hierarchy

• H2 major sections: border-left: 6px solid #0288d1; (thick border for major parts)
• H3 subsections: border-left: 4px solid #0288d1; (thinner border for content within sections)
• Hero cells: No border (full-width hero styling)
• Transition cells: border-left: 4px solid #0288d1; (matches subsection weight)

Standard Container Patterns

H2 Major Section (NO section tag):

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

  <h2 style="color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;">🎯 Section Title</h2>

  <p style="font-size: 16px; line-height: 1.8;">Body text content here...</p>

</div>

IMPORTANT: Do NOT wrap cells in <section> tags - they cause overlay jumping between slides.

H3 Subsection (standalone):

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 4px solid #0288d1; color: #212121;">

  <h3 style="color: #0d47a1; font-size: 26px; font-weight: 700; margin-bottom: 20px; display: flex; align-items: center; gap: 12px;">
    <span style="font-size: 28px;">✨</span>
    Subsection Title
  </h3>

  <p style="font-size: 16px; line-height: 1.8;">Body text content here...</p>

</div>

Hero Cell (title page):

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); color: white; border-radius: 16px; padding: 48px; text-align: center; margin: 0 0; box-shadow: 0 8px 20px rgba(0,0,0,0.25); color: #212121;">
  <h1 style="font-size: 48px; font-weight: 800; margin: 0 0 16px 0; display: flex; align-items: center; justify-content: center; gap: 16px;">
    <span style="font-size: 56px;">🎯</span>
    <span>Presentation Title</span>
  </h1>
  <p style="font-size: 20px; margin: 16px 0; opacity: 0.95; font-weight: 300;">
    Compelling subtitle or tagline
  </p>
</div>

Block Wrapping Pattern

CRITICAL: All EDS blocks MUST be wrapped INSIDE styled divs, not as siblings.

Blocks inherit dark background from ipynb-viewer if not properly wrapped:

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

  <h2 style="color: #0d47a1; font-size: 28px; font-weight: 700; margin-bottom: 24px;">Section Title</h2>

  <!-- Optional explanation box -->
  <div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 20px; margin: 0 0 24px 0; border-left: 4px solid #0288d1; color: #212121;">
    Explanation text about the block demonstration
  </div>

  <!-- Block INSIDE the container -->
  <div class="block-name block">
    <!-- block content -->
  </div>

  <script type="module">
    const block = document.querySelector('.block-name.block');
    const module = await import('/blocks/block-name/block-name.js');
    await module.default(block);
  </script>

</div> <!-- Close container AFTER block -->

Common Mistakes to Avoid

1. ❌ Using markdown headings (##, ###) - they render grey
2. ❌ Using <section> tags to wrap cells - causes overlay jumping between slides
3. ❌ Placing blocks as siblings to styled divs - they inherit dark background
4. ❌ Forgetting color: #212121; on gradient divs - text fades
5. ❌ Using vertical margins (margin: 32px 0;) - creates black gaps
6. ❌ Inconsistent H3 margin-bottom (always use 20px, not 24px)
7. ❌ Inconsistent colors across cells

Inline HTML Styling

Design System

Apply consistent inline HTML styling to all markdown cells for professional presentation:

Standard Color Palette:

{
  heading: '#0d47a1',      // Dark Blue (all headings)
  text: '#212121',         // Dark Gray (all body text)
  border: '#0288d1',       // Blue (left borders)
  gradient_start: '#e3f2fd', // Light Blue (gradient start)
  gradient_end: '#bbdefb',   // Medium Blue (gradient end)

  // Legacy/optional colors:
  primary: '#1976d2',      // Material Blue
  secondary: '#dc004e',    // Material Pink
  success: '#2e7d32',      // Green
  warning: '#ed6c02',      // Orange
  background: '#f5f5f5',   // Light Gray
  surface: '#ffffff'       // White
}

Styling Patterns

Hero Header:

<div style="background: linear-gradient(135deg, #1976d2 0%, #1565c0 100%); color: white; border-radius: 16px; padding: 48px; text-align: center; margin: 32px 0; box-shadow: 0 8px 16px rgba(0,0,0,0.2);">
<h1 style="font-size: 48px; font-weight: 800; margin: 0 0 16px 0;">
🗺️ Presentation Title
</h1>
<p style="font-size: 20px; margin: 16px 0; opacity: 0.95;">
Your compelling subtitle or tagline
</p>
</div>

Content Card:

<div style="background: white; border-radius: 12px; padding: 28px; margin: 20px 0; box-shadow: 0 2px 8px rgba(0,0,0,0.08);">
<h3 style="color: #1976d2; font-size: 24px; font-weight: 700; margin-bottom: 20px;">Section Title</h3>
<div style="color: #212121; line-height: 1.8; font-size: 16px;">
Your content here with proper typography
</div>
</div>

Block Wrapper (for EDS blocks):

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

<h3 style="color: #0d47a1; font-size: 26px; font-weight: 700; margin-bottom: 16px;">What this demonstrates</h3>

<p>Explanatory text before the EDS block</p>

<div class="cards block">
  <!-- Block HTML here -->
</div>

<script type="module">
  const block = document.querySelector('.cards.block');
  const module = await import('/blocks/cards/cards.js');
  await module.default(block);
</script>

</div>

List with Icons (Compact Spacing):

<ul style="list-style: none; padding: 0; margin: 0;">
  <li style="padding: 12px 0; border-bottom: 1px solid rgba(0,0,0,0.08); font-size: 16px; display: flex; align-items: center; gap: 12px;">
    <span style="font-size: 20px;">✅</span>
    <span>List item text</span>
  </li>
  <!-- Remove border-bottom from last item -->
  <li style="padding: 12px 0; font-size: 16px; display: flex; align-items: center; gap: 12px;">
    <span style="font-size: 20px;">✅</span>
    <span>Last list item</span>
  </li>
</ul>

Typography Scale

• H1 (Hero Title): 48px, font-weight: 800, emoji: 56px
• H2 (Major Sections): 28px, font-weight: 700, emoji: 32px
• H3 (Subsections): 26px, font-weight: 700, emoji: 28px
• Body Text: 16px, line-height: 1.8
• TOC Links: 18px, font-weight: 500
• List Icons: 20px (emojis)
• Code: Courier New, monospace

Spacing System

• Container Padding: 32px (all content containers)
• Hero Padding: 48px (title cells)
• H2 Margin-bottom: 24px
• H3 Margin-bottom: 20px
• Paragraph Margin-bottom: 16px-24px
• List Item Padding: 12px vertical, with border separators
• TOC Item Padding: 10px vertical, 8px 12px for links
• Flexbox Gap: 12px (heading emoji spacing)
• Border Radius: 12px (standard), 16px (hero cells)

Interactive Elements

Hover Effects:

• Background transitions on links
• Color changes on buttons
• Shadow depth changes on cards

Best Practices:

• ✅ Use CSS :hover pseudo-class - Inline JavaScript event handlers (onmouseover, onmouseout) are blocked by browser security
• ✅ Use <style> tags with classes - Define reusable classes for hover states
• ✅ Apply transition - For smooth animations (e.g., transition: background 0.2s)
• ✅ Maintain accessibility - Proper contrast ratios and focus states

Security Note: Browsers block inline JavaScript event handlers when content is inserted via innerHTML (which ipynb-viewer uses). Always use CSS :hover instead of onmouseover/onmouseout.

Converting Code Cells

Original Code Cell

const { testBlock } = await import('/scripts/ipynb-helpers.js');
const block = await testBlock('accordion', content);
return block.outerHTML;

Converted to Markdown

<div style="background: linear-gradient(135deg, #e3f2fd 0%, #bbdefb 100%); border-radius: 12px; padding: 32px; margin: 0 0; border-left: 6px solid #0288d1; color: #212121;">

<h3 style="color: #0d47a1; font-size: 26px; font-weight: 700; margin-bottom: 16px;">Code Example: Testing Accordion Block</h3>

<p>This example demonstrates how to test the accordion block programmatically:</p>

**Original code:**
\```javascript
const { testBlock } = await import('/scripts/ipynb-helpers.js');
const block = await testBlock('accordion', content);
return block.outerHTML;
\```

**What it does:**
1. Imports the testBlock helper function
2. Tests the accordion block with provided content
3. Returns the rendered HTML

**Result:** The accordion block is decorated and ready for display.

---

**Note:** In presentation mode, code is shown for reference only. See the live accordion demonstration below:

<div class="accordion block">
  <!-- Actual working accordion here -->
</div>

<script type="module">
  const block = document.querySelector('.accordion.block');
  const module = await import('/blocks/accordion/accordion.js');
  await module.default(block);
</script>

</div>

Conversion Rules

1. Show the code - Display original code in fenced code block
2. Explain the purpose - What does this code do?
3. Describe the result - What was the expected outcome?
4. Provide alternative - Show the working result via embedded block

Best Practices

Visual Design

• Use emojis for section headers (🎯, 📊, 🚀, ✨, 💡)
• Break content into digestible chunks
• Use blocks for interactive elements
• Add horizontal rules (---) between major sections
• Use bold and italic for emphasis

Choosing Between Auto-Wrapping and Manual HTML

Both presentation (non-interactive) and educational (interactive) notebooks can use either approach.

Auto-wrapping (pure markdown):

• ✅ 90% less code to write
• ✅ Fast content creation
• ✅ Consistent default styling
• ❌ ONLY works in notebook mode (| IPynb Viewer (notebook) |)
• ❌ Limited design control

Manual HTML styling (inline styles):

• ✅ Works in ALL display modes (basic, paged, autorun, notebook)
• ✅ Precise control over visual appearance
• ✅ Complex layouts with nested blocks
• ✅ Professional polish
• ❌ Slower authoring (10x more code)

Decision matrix:

Factor	Use Auto-Wrapping	Use Manual HTML
Display mode	Notebook mode	Any mode (paged, autorun, basic, notebook)
Priority	Speed/simplicity	Design control/polish
Content	Simple structure	Complex layouts
Notebook type	Both presentation & educational	Both presentation & educational

Key insight: "Presentation" refers to non-interactive style (no runnable code), NOT a display mode. Auto-wrapping works for presentation notebooks displayed in notebook mode.

Mixing Both Approaches: You can combine auto-wrapping with custom HTML in the same notebook for maximum flexibility:

• Use pure markdown (auto-wrapped) for most cells
• Add custom HTML wrapper for specific cells needing special styling
• Example use cases:
  • Custom gradient for hero sections
  • Special highlight colors for key messages
  • Unique layouts for specific sections
  • Brand-specific color schemes

<!-- Most cells: pure markdown (auto-wrapped) -->
# Section Title

Regular content here...

<!-- Special cell: custom HTML for emphasis -->
<div style="background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); border-radius: 12px; padding: 48px; margin: 0; text-align: center; color: white;">

<h2 style="font-size: 36px; font-weight: 800; margin: 0;">🎯 Key Takeaway</h2>

<p style="font-size: 20px;">Custom styling for this important message</p>

</div>

This hybrid approach gives you speed (pure markdown) with flexibility (custom HTML) where needed.

Action Cards for Navigation (NEW):

Create beautiful navigation links using pure markdown with action cards:

# 🎯 Product Launch Presentation

Discover our revolutionary new features.

<!-- action-cards -->

- [Overview](#)
- [Key Features](#)
- [Pricing](#)

How it works:

1. Add <!-- action-cards --> HTML comment in your markdown cell
2. Follow with a markdown list of links using (#) as placeholder
3. Write link text that matches heading text somewhere in your notebook
4. Links are automatically resolved at runtime - JavaScript searches all cells for matching headings and updates hrefs
5. All cards use consistent blue styling

Important: The <!-- action-cards --> marker only applies to the first list that follows it. Any subsequent lists in the same cell will remain as normal bullet lists.

Example matching:

• [Overview](#) finds heading containing "Overview" (like "## Overview" or "### 📊 Overview Section")
• [Key Features](#) finds heading containing "Key Features" (like "## Section 2: Key Features")
• Link text doesn't need exact match - searches for headings that contain your link text

Best Practices:

• ✅ Use specific link text: [Section 1: Overview](#) instead of just [Overview](#)
• ✅ Make link text unique to avoid ambiguity
• ⚠️ If multiple headings match, it picks the first one found (in cell order)
• 💡 Tip: Use section numbers or descriptive prefixes to ensure unique matches

Features:

• ✅ Pure markdown - no HTML required
• ✅ Works in any cell type (hero, content, intro, transition)
• ✅ Smart link resolution - No hardcoded cell IDs needed
• ✅ Automatically finds matching headings at runtime
• ✅ Consistent blue design - professional appearance
• ✅ Hover effects with animated arrows (→)
• ✅ Perfect for presentation navigation and agendas

When to use action cards in presentations:

• Hero cells with section navigation
• Presentation agenda or table of contents
• Call-to-action sections
• Multi-section flow navigation
• Quick access menus

Link Types: Smart Navigation vs Repository Links

The ipynb-viewer block supports two independent link systems for different purposes:

Smart Navigation Links (Internal Presentation Navigation)

Smart linking works for ANY link with (#) as the href, not just action cards. Perfect for presentation flow control.

Activates when: Link has href="#" (hash placeholder) Works in: Action cards, inline text, buttons, any link element

Examples:

# Regular presentation navigation
Proceed to [Next Slide](#) or review [Previous Slide](#).

# In agenda/TOC
1. [Introduction](#)
2. [Problem Statement](#)
3. [Solution Overview](#)
4. [Demo](#)

# Action cards (same smart linking)
<!-- action-cards -->
- [Product Overview](#)
- [Key Features](#)
- [Pricing](#)

How it works:

• JavaScript searches all cells for headings matching link text
• Case-insensitive matching, ignores emojis
• Resolves to #cell-{index} at runtime
• No hardcoded cell IDs - presentation adapts if slides reorder

Best for presentations:

• Slide-to-slide navigation
• Table of contents / agenda
• Call-to-action buttons
• Section jumps

Repository Links (External Resources)

Links ending in .md automatically convert to GitHub URLs. Perfect for "learn more" or reference materials.

Activates when: Link ends in .md Requires: repo field in notebook metadata

Setup:

{
  "metadata": {
    "repo": "https://github.com/username/project"
  }
}

Examples:

For technical details, see [Architecture](docs/architecture.md)

Read the [Implementation Guide](docs/guide.md)

Download [User Manual](docs/user-manual.md)

Best for presentations:

• Technical documentation links
• "Learn more" resources
• Follow-up materials
• Supporting documentation

Using Both in Presentations

Mix both link types for effective presentations:

# 🎯 Product Demo

Presentation strategy:

• Smart links keep viewers in the presentation flow (same page)
• Repo links provide optional deep dives (new tab)
• Clear separation between presentation content and reference materials

Content Organization

• Start with title and overview
• Table of contents for long presentations
• Group related content in blocks
• End with call-to-action or summary
• Use hash links for navigation

Performance

• Limit to 1-3 blocks per cell (avoid overwhelming)
• Use simple inline scripts (no heavy libraries)
• Keep markdown cells focused (one topic per cell)
• Test in paged mode for smooth navigation

Accessibility

• Use semantic HTML in blocks
• Provide alt text for images
• Clear heading hierarchy (H1 → H2 → H3)
• Descriptive link text

Examples

See resources/complete-examples.md for full presentation notebook examples.

Workflow

Step 1: Plan Structure

Identify:

• Main topic and title
• Key sections (3-7 sections ideal)
• Which blocks fit each section
• Navigation needs

Step 2: Create Metadata

Set up notebook metadata with title, description, author, etc.

Step 3: Build Cells

For each section:

1. Markdown header
2. Content explanation
3. Embedded block (if needed)
4. Inline script to activate block

Step 4: Add Navigation

• Table of contents at start
• Hash links between sections
• "Back to top" or "Next section" links

Step 5: Test

• View in default mode (scrollable)
• View in paged mode (with "Start Reading")
• Test all interactive blocks
• Verify links work

Technical Details

Block Initialization Pattern

All blocks follow this pattern:

1. HTML structure in markdown
2. Inline script with module import
3. Decoration by calling default export

const block = document.querySelector('.block-name.block');
const module = await import('/blocks/block-name/block-name.js');
await module.default(block);

Styling

Blocks automatically load their CSS. For custom styling:

<style>
.custom-class {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  padding: 2rem;
  border-radius: 12px;
}
</style>

<div class="custom-class">
  Custom styled content
</div>

Loading CSS

If needed, manually load CSS:

<script>
const link = document.createElement('link');
link.rel = 'stylesheet';
link.href = '/blocks/block-name/block-name.css';
document.head.appendChild(link);
</script>

Overlay Styling (Auto-Applied)

The ipynb-viewer block automatically handles consistent styling for paged presentations:

Font Consistency

All text uses selective font inheritance (fixed in v1.0.2):

• Only font-family inherits, not font-size, margin, padding
• Inline styles with explicit sizes are preserved
• No font jumping between slides while respecting cell styling

Fixed Position & Height

Overlay stays perfectly still when navigating (fixed in v1.0.2):

• Pinned at 5vh from top (not vertically centered)
• Content box locked at exactly 85vh tall
• Zero movement regardless of content size
• Content scrolls internally within fixed cell area

Navigation Hover Effects

Navigation links work with CSS hover (fixed in v1.0.2):

• Use inline styles on <a> elements, not <style> tag classes
• CSS :hover selector automatically applies to nav links
• No inline JavaScript needed (onmouseover/onmouseout don't work)

Note: These fixes apply automatically to all presentations. No additional configuration needed.

Troubleshooting

Fonts Look Inconsistent

Problem: Heading sizes change between slides

Solution: No action needed - fixed in v3 (Jan 2025). The ipynb-viewer now uses font-size: revert !important to respect inline styles. Headings with inline styles (e.g., style="font-size: 26px") display at their specified sizes.

If Still Seeing Issues: Ensure you're using latest ipynb-viewer CSS and clear browser cache.

Overlay Jumps When Navigating

Problem: Overlay resizes or moves vertically between slides

Solution: Ensure cells follow consistent structure:

• ✅ NO <section> tags - These add HTML structure causing height differences
• ✅ Consistent H2/H3 margins - H2: 24px, H3: 20px (not 24px)
• ✅ Same border hierarchy - H2 cells: 6px, H3 cells: 4px

The ipynb-viewer overlay positioning is fixed (v4, Jan 2025):

• Vertically centered with fixed 85vh height using !important
• Content scrolls inside cell area, overlay never resizes
• Multiple overlays prevented by automatic cleanup
• Cell structure consistency prevents content-level jumping

If Still Seeing Issues: Check that all cells have consistent structure and clear browser cache.

Multiple Overlays or Unpredictable Behavior

Problem: Overlay appears duplicated or behaves strangely after page refresh

Solution: No action needed - fixed in v3 (Jan 2025). The ipynb-viewer now removes existing overlays before creating new ones, preventing stacking.

Navigation Hover Not Working

Problem: TOC links don't change background on hover

Solution: Navigation links are automatically styled by ipynb-viewer CSS. Use nav[aria-label="Presentation navigation"] wrapper and links will get proper styling automatically.

Note: TOC should only be added if explicitly requested. The template does not include one by default.
