HTML Presentation Template

Reference architecture for generating slide presentations. Every presentation follows this structure.

Required JavaScript Features

Every presentation must include:

SlidePresentation Class — Main controller with:
- Keyboard navigation (arrows, space, page up/down)
- Touch/swipe support
- Mouse wheel navigation
- Progress bar updates
- Navigation dots
Intersection Observer — For scroll-triggered animations:
- Add .visible class when slides enter viewport
- Trigger CSS transitions efficiently
Optional Enhancements (match to chosen style):
- Custom cursor with trail
- Particle system background (canvas)
- Parallax effects
- 3D tilt on hover
- Magnetic buttons
- Counter animations

Code Quality

Comments: Every section needs clear comments explaining what it does and how to modify it.

Accessibility:

Semantic HTML (<section>, <nav>, <main>)
Keyboard navigation works fully
ARIA labels where needed
prefers-reduced-motion support (included in viewport-base.css)

File Structure

Single presentations:

presentation.html    # Self-contained, all CSS/JS inline
assets/              # Images only, if any

Multiple presentations in one project:

[name].html
[name]-assets/
