## What it does

The skill kicks in when you ask for slides, a presentation, a deck or a slideshow. You get two files: an HTML file that loads reveal.js from a CDN, and a CSS file with the styling. No bundler, no build command — the HTML opens straight in a browser.

A script does the scaffolding: `scripts/create-presentation.js`. Pass `--slides N` for N horizontal slides, or `--structure 1,1,d,3,1,d,1` to mix single slides, vertical stacks and section dividers. The script also copies `base-styles.css` into your presentation folder as `styles.css`, so you edit the theme variables from there.

The skill insists the agent state a design approach before writing any code. Font sizes should be set in `pt` rather than `em`, `rem` or `px`, since slides are fixed-size. If your project already ships a CSS framework with its own type scale, that is worth checking before the deck inherits it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ryanbbrown/revealjs-skill --skill revealjs -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/revealjs/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/revealjs/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ryanbbrown/revealjs-skill --skill revealjs -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/revealjs/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ryanbbrown/revealjs-skill --skill revealjs -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/revealjs/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/ryanbbrown/revealjs-skill/tree/HEAD/skills/revealjs/SKILL.md

## When to use it
- turn written content into slides without hand-coding layouts
- build a deck with section dividers and nested vertical slides
- pick a colour palette that fits the talk
- add code highlighting and speaker notes to slides
- get a single HTML file that opens without a build

## Example prompts
- make a 12-slide presentation about our quarterly report
- build a deck with section dividers and vertical slides inside
- create slides for a talk with code highlighting and speaker notes

# Reveal.js Presentations

Create HTML presentations using reveal.js. No build step required - just open the HTML in a browser.

## What You Create

A reveal.js presentation consists of:

1. **HTML file** - Contains slides and loads reveal.js from CDN
2. **CSS file** - Custom styles for layouts, colors, typography, and components

## Design Principles

**CRITICAL**: Before creating any presentation, analyze the content and choose appropriate design elements:

1. **Consider the subject matter**: What is this presentation about? What tone, industry, or mood does it suggest?
2. **Check for branding**: If the user mentions a company/organization, consider their brand colors and identity
3. **Match palette to content**: Select colors that reflect the subject
4. **State your approach**: Explain your design choices before writing code

**Requirements**:
- ✅ State your content-informed design approach BEFORE writing code
- ✅ Use web-safe fonts (Arial, Helvetica, Georgia, Verdana, etc.) or Google Fonts via `@import` in CSS
- ✅ Create clear visual hierarchy through size, weight, and color
- ✅ Ensure readability: strong contrast, appropriately sized text, clean alignment
- ✅ Be consistent: repeat patterns, spacing, and visual language across slides
- ✅ **Always use `pt` (points) for font sizes** - slides are fixed-size, so `pt` is predictable and familiar (like PowerPoint/Keynote). Never use `em`, `rem`, or `px` for font sizes.

### Color Palette Selection

**Choosing colors creatively**:
- **Think beyond defaults**: What colors genuinely match this specific topic? Avoid autopilot choices.
- **Consider multiple angles**: Topic, industry, mood, energy level, target audience, brand identity (if mentioned)
- **Be adventurous**: Try unexpected combinations - a healthcare presentation doesn't have to be green, finance doesn't have to be navy
- **Build your palette**: Pick 3-5 colors that work together (dominant colors + supporting tones + accent)
- **Ensure contrast**: Text must be clearly readable on backgrounds

**Example color palettes** (use these to spark creativity - choose one, adapt it, or create your own):

1. **Classic Blue**: Deep navy (#1C2833), slate gray (#2E4053), silver (#AAB7B8), off-white (#F4F6F6)
2. **Teal & Coral**: Teal (#5EA8A7), deep teal (#277884), coral (#FE4447), white (#FFFFFF)
3. **Bold Red**: Red (#C0392B), bright red (#E74C3C), orange (#F39C12), yellow (#F1C40F), green (#2ECC71)
4. **Warm Blush**: Mauve (#A49393), blush (#EED6D3), rose (#E8B4B8), cream (#FAF7F2)
```
