The Meetup Talk That Built Itself: Zero-Dependency HTML Slides

Key Takeaway

We built a keynote-quality presentation as a single HTML file — no npm, no build tools, no dependencies — with animation-rich transitions and PDF export, for the Mr.Chief Paris Meetup with 93+ attendees.

The Problem

Presentation tools are either too simple or too complicated.

PowerPoint and Google Slides give you static rectangles. Reveal.js gives you web-native slides but requires npm, Node.js, a build pipeline, and a package.json longer than your talk. Keynote looks great but locks you into macOS and proprietary formats.

For the Mr.Chief Paris Meetup, we needed a presentation that:

  • Runs on any machine (presenter's laptop could die — use anyone's)
  • Has smooth, non-cheesy animations
  • Works in any browser without installing anything
  • Can be hosted as a URL for attendees
  • Exports to PDF for handouts
  • Can be built and iterated on in minutes, not hours

The constraint: zero external dependencies. One HTML file. Double-click to open. That's it.

The Solution

The create-html-slides skill in Mr.Chief generates self-contained HTML presentations with inline CSS and JavaScript. Keynote-quality animations. Responsive layout. Keyboard navigation. PDF export. All in a single file.

We described what we wanted. The agent built it.

The Process (with code/config snippets)

The prompt:

View details
Create an HTML presentation for the Mr.Chief Paris Meetup.

Theme: Dark mode, tech aesthetic, subtle gradients
Slides: 15 slides covering agent architecture, live demos, roadmap
Style: Minimal text, big visuals, code snippets with syntax highlighting
Animations: Fade-in for content, slide transitions, code typewriter effect

Requirements:
- Single HTML file, zero dependencies
- Keyboard navigation (arrow keys + spacebar)
- Progress bar at bottom
- Slide counter
- PDF export button
- Responsive (works on projector AND phone)

The agent generates a complete HTML file. Here's the core structure:

At the meetup, 93+ attendees watched the presentation. Several asked how we built it. "It's one HTML file" got a laugh. Then they wanted to know how to do it themselves.

Try It Yourself

Describe your presentation: topic, number of slides, visual theme, and any special elements (code blocks, diagrams, animations).

The agent generates a single HTML file. Open it in a browser. Present.

If you want to iterate, just ask for changes. The agent modifies the same file. No rebuild, no recompile, no dependency hell.
