Presentation Skill

Creates standalone HTML slide deck presentations with CSS animations, keyboard/click/swipe navigation, bullet reveal, mouse parallax, and polished visual design. Single file, no dependencies, works anywhere.

Step 1: Choose a Mode

Ask the user how they want to work:

Full generation: User provides content/outline upfront → Claude generates the entire presentation in one shot. Best when the user already knows what they want to say.
Interactive step-by-step: Claude scaffolds the framework first, then builds slides one at a time — user reviews each slide before moving to the next. Best when the user is still figuring out the story or wants tight control.

Step 2: Content & Structure (THE MOST IMPORTANT STEP)

Before writing any code, deeply understand what the presentation is actually saying.

Ask the user to provide source material — any of:

A document, outline, or notes about the topic
A rough slide-by-slide outline
Key talking points, stats, or quotes
An existing presentation to redesign
A brain dump of everything they want to cover

Then collaboratively build the slide outline:

For each slide: choose a type, headline, body content, and special elements
Suggest a narrative arc: hook → context → key content → details → closing
Flag where bullet-reveal slides help (dense content needing progressive disclosure)
Identify which slides need images/assets vs. pure text
Confirm final slide count and order before proceeding

This step makes or breaks the presentation. Spend the most time here.

Available slide types

Type	Class	Use Case
Title	`.slide-title`	Opening — large heading, subtitle, decorative shapes
Speaker/Bio	`.slide-speaker`	Introduce presenter — avatar, name, role, glass card
Question	`.slide-familiar`	Audience engagement — large centered question
Bullet Reveal	`.slide-learn`	Key points, agendas — progressive reveal with `data-bullets`
Tool/Badge Grid	`.slide-setup`	Tools, tech, logos — grid of badge cards
Workflow/Flow	`.slide-flow`	Processes, steps — connected boxes with arrows
Two-Column	`.slide-llm`	Text + image — split layout
Team/Grid	`.slide-speakers`	Meet the team — photo grid with names/roles
Glossary	`.slide-gloss`	Definitions — large term + definition
Closing/CTA	`.slide-closing`	Final slide — large text, call to action

For detailed HTML templates of each type, see [slide-types.md](slide-types.md).

Step 3: Design Brief

Gather style direction from the user:

Colors: brand colors, or suggest a palette (5-6 hex values with roles: primary, secondary, accent, background-light, background-dark, text)
Fonts: heading + body font families (Google Fonts or system fonts)
Vibe: minimal / editorial / glassmorphism / bold / corporate
Assets: logos, images, photos to embed

Produce a brief with:

Color palette with CSS variable names and hex values
Typography scale (heading-xl, heading-lg, heading-md, subtitle, body-text)
Font families and weights
Spacing rhythm (slide padding, element gaps)
Animation style (subtle vs. dramatic)
One-sentence visual direction
Slide-to-theme mapping (which slides get which background color)

For CSS/typography/animation defaults and templates, see [framework-reference.md](framework-reference.md).

Step 4: Generate the Framework

Create a single standalone HTML file with embedded <style> and <script>.

The file structure is:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>[Presentation Title]</title>
  [Google Fonts link]
  <style>
    /* Reset, design tokens, slide system, themes, shapes,
       animations, typography, UI chrome, slide-specific styles,
       responsive breakpoint */
  </style>
</head>
<body>
  <div class="presentation">
    <!-- Slides go here -->
  </div>
  <!-- Progress bar, slide counter, nav hint -->
  <script>
    /* IIFE-based navigation engine */
  </script>
</body>
</html>

For the complete CSS architecture and JS navigation engine templates, see [framework-reference.md](framework-reference.md).

Step 5: Build Slides

Using the templates from [slide-types.md](slide-types.md):

Full generation mode: Create all slides at once based on the outline from Step 2
Interactive mode: One slide at a time — write the HTML, let the user review, adjust, then move to the next

For every slide:

Use the appropriate section.slide with theme class (.slide--primary, .slide--secondary, .slide--light)
Set data-theme="dark" or data-theme="light" for nav UI color adaptation
Add .anim classes to all content elements for entrance animations
Apply stagger delays (.anim-d1 through .anim-d8) in visual reading order
Add decorative shapes with entrance directions (.shape-enter-left, etc.)
Include .slide-footer with consistent content on every slide
For bullet-reveal slides: set data-bullets="N" and use <li data-bullet="N"> elements

Step 6: Polish & Review

Step 7: Export

Default: standalone HTML — single file with base64-embedded images and assets. Works anywhere, no server needed.

To embed images as base64:

<img src="data:image/png;base64,[base64-data]" alt="...">

Optionally offer:

Dev version: external image references for easier editing
Individual slides: separate HTML files per slide for modular use

Key Patterns

For design patterns, animation tips, and hard-won insights from building presentations with this framework, see [learnings.md](learnings.md).

Quick reference

Easing: cubic-bezier(0.16, 1, 0.3, 1) (expo-out) for all transitions
Stagger: .anim-d1 (0.1s) through .anim-d8 (1.1s)
Shapes: absolute positioned, mix-blend-mode: overlay, floating keyframe animations
Glass: backdrop-filter: blur(28px) + semi-transparent white + subtle border
Typography: clamp() for fluid sizing across projector/laptop/tablet
Parallax: --mx/--my CSS variables tracked on mousemove
Transitions: 700ms lockout via isTransitioning flag
