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
Inline Editing (only if user opted in during Phase 1 — skip entirely if they said No):
- Edit toggle button (hidden by default, revealed via hover hotzone or E key)
- Auto-save to localStorage
- Export/save file functionality
- See "Inline Editing Implementation" section below

Inline Editing Implementation (Opt-In Only)

If the user chose "No" for inline editing in Phase 1, do NOT generate any edit-related HTML, CSS, or JS.

Do NOT use CSS ~ sibling selector for hover-based show/hide. The CSS-only approach (edit-hotzone:hover ~ .edit-toggle) fails because pointer-events: none on the toggle button breaks the hover chain: user hovers hotzone -> button becomes visible -> mouse moves toward button -> leaves hotzone -> button disappears before click.

Required approach: JS-based hover with 400ms delay timeout.

HTML:

<div class="edit-hotzone"></div>
<button class="edit-toggle" id="editToggle" title="Edit mode (E)">Edit</button>

CSS (visibility controlled by JS classes only):

/* Do NOT use CSS ~ sibling selector for this!
   pointer-events: none breaks the hover chain.
   Must use JS with delay timeout. */
.edit-hotzone {
  position: fixed;
  top: 0;
  left: 0;
  width: 80px;
  height: 80px;
  z-index: 10000;
  cursor: pointer;
}
.edit-toggle {
  opacity: 0;
  pointer-events: none;
  transition: opacity 0.3s ease;
  z-index: 10001;
}
.edit-toggle.show,
.edit-toggle.active {
  opacity: 1;
  pointer-events: auto;
}

JS (three interaction methods):

// 1. Click handler on the toggle button
document.getElementById("editToggle").addEventListener("click", () => {
  editor.toggleEditMode();
});

// 2. Hotzone hover with 400ms grace period
const hotzone = document.querySelector(".edit-hotzone");
const editToggle = document.getElementById("editToggle");
let hideTimeout = null;

hotzone.addEventListener("mouseenter", () => {
  clearTimeout(hideTimeout);
  editToggle.classList.add("show");
});
hotzone.addEventListener("mouseleave", () => {
  hideTimeout = setTimeout(() => {
    if (!editor.isActive) editToggle.classList.remove("show");
  }, 400);
});
editToggle.addEventListener("mouseenter", () => {
  clearTimeout(hideTimeout);
});
editToggle.addEventListener("mouseleave", () => {
  hideTimeout = setTimeout(() => {
    if (!editor.isActive) editToggle.classList.remove("show");
  }, 400);
});

// 3. Hotzone direct click
hotzone.addEventListener("click", () => {
  editor.toggleEditMode();
});

// 4. Keyboard shortcut (E key, skip when editing text)
document.addEventListener("keydown", (e) => {
  if (
    (e.key === "e" || e.key === "E") &&
    !e.target.getAttribute("contenteditable")
  ) {
    editor.toggleEditMode();
  }
});

CRITICAL: exportFile() must strip edit state before capturing outerHTML.

When the user presses Ctrl+S in edit mode, document.documentElement.outerHTML captures the live DOM — including body.edit-active, contenteditable="true" on every text element, and .active/.show classes on the toggle button and banner. Anyone opening the saved file sees dashed outlines, a checkmark button, and an edit banner, as if permanently stuck in edit mode.

Always implement exportFile() like this:

exportFile() {
    // Temporarily strip edit state so the saved file opens cleanly
    const editableEls = Array.from(document.querySelectorAll('[contenteditable]'));
    editableEls.forEach(el => el.removeAttribute('contenteditable'));
    document.body.classList.remove('edit-active');

    // Also strip UI classes from toggle button and banner
    const editToggle = document.getElementById('editToggle');
    const editBanner = document.querySelector('.edit-banner');
    editToggle?.classList.remove('active', 'show');
    editBanner?.classList.remove('active', 'show');

    const html = '<!DOCTYPE html>\n' + document.documentElement.outerHTML;

    // Restore edit state so the user can keep editing
    document.body.classList.add('edit-active');
    editableEls.forEach(el => el.setAttribute('contenteditable', 'true'));
    editToggle?.classList.add('active');
    editBanner?.classList.add('active');

    const blob = new Blob([html], { type: 'text/html' });
    const a = document.createElement('a');
    a.href = URL.createObjectURL(blob);
    a.download = 'presentation.html';
    a.click();
    URL.revokeObjectURL(a.href);
}

Image Pipeline (Skip If No Images)

If user chose "No images" in Phase 1, skip this entirely. If images were provided, process them before generating HTML.

Dependency: pip install Pillow

Image Processing

from PIL import Image, ImageDraw

# Circular crop (for logos on modern/clean styles)
def crop_circle(input_path, output_path):
    img = Image.open(input_path).convert('RGBA')
    w, h = img.size
    size = min(w, h)
    left, top = (w - size) // 2, (h - size) // 2
    img = img.crop((left, top, left + size, top + size))
    mask = Image.new('L', (size, size), 0)
    ImageDraw.Draw(mask).ellipse([0, 0, size, size], fill=255)
    img.putalpha(mask)
    img.save(output_path, 'PNG')

# Resize (for oversized images that inflate HTML)
def resize_max(input_path, output_path, max_dim=1200):
    img = Image.open(input_path)
    img.thumbnail((max_dim, max_dim), Image.LANCZOS)
    img.save(output_path, quality=85)

Situation	Operation
Square logo on rounded aesthetic	`crop_circle()`
Image > 1MB	`resize_max(max_dim=1200)`
Wrong aspect ratio	Manual crop with `img.crop()`

Save processed images with _processed suffix. Never overwrite originals.

Image Placement

Use direct file paths (not base64) — presentations are viewed locally:

<img src="assets/logo_round.png" alt="Logo" class="slide-image logo" />
<img
  src="assets/screenshot.png"
  alt="Screenshot"
  class="slide-image screenshot"
/>

.slide-image {
  max-width: 100%;
  max-height: min(50vh, 400px);
  object-fit: contain;
  border-radius: 8px;
}
.slide-image.screenshot {
  border: 1px solid rgba(255, 255, 255, 0.1);
  border-radius: 12px;
  box-shadow: 0 8px 32px rgba(0, 0, 0, 0.3);
}
.slide-image.logo {
  max-height: min(30vh, 200px);
}

Adapt border/shadow colors to match the chosen style's accent. Never repeat the same image on multiple slides (except logos on title + closing).

Placement patterns: Logo centered on title slide. Screenshots in two-column layouts with text. Full-bleed images as slide backgrounds with text overlay (use sparingly).

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/
