The Browser is a Marvelous Thing! 🌐

An interactive presentation showcasing modern browser capabilities and hidden web features.

🎯 Overview

This presentation demonstrates the incredible evolution of web browsers in 2024, featuring:

• Underutilized HTML elements (Dialog, Details/Summary, Datalist)
• Powerful Web APIs (File System Access, View Transitions, Intersection Observer)

🏗️ Architecture: Manifest-Based Slide System

This presentation uses a manifest-based architecture that provides flexible slide management without the limitations of traditional numeric indexing.

✨ Key Benefits

• Simple Removal: Remove slides without affecting others
• Semantic Organization: Descriptive file names and metadata
• Dynamic Management: Enable/disable slides without deletion
• Section Support: Organize slides into logical groups
• Maintainable: Clear separation of content and structure

🔧 Slide Management

Adding a New Slide

1. Create your slide HTML file in the slides/ directory
2. Add an entry to the slides array in manifest.json:

{
  "id": "my-new-slide",
  "title": "My Amazing New Slide",
  "file": "my-new-slide.html",
  "enabled": true,
  "section": "introduction",
  "description": "Description of the slide content"
}

3. The slide will automatically appear in the presentation!

Removing a Slide

• Temporary: Set "enabled": false in the manifest
• Permanent: Remove the entry from the manifest and delete the HTML file
