Frontend Slides

A Claude Code skill for creating stunning, animation-rich HTML presentations — from scratch or by converting PowerPoint files.

What This Does

Frontend Slides helps non-designers create beautiful web presentations without knowing CSS or JavaScript. It uses a "show, don't tell" approach: instead of asking you to describe your aesthetic preferences in words, it generates visual previews and lets you pick what you like.

Here is a deck about the skill, made through the skill:

Key Features

• Zero Dependencies — Single HTML files with inline CSS/JS. No npm, no build tools, no frameworks.
• Visual Style Discovery — Can't articulate design preferences? No problem. Pick from generated visual previews.
• PPT Conversion — Convert existing PowerPoint files to web, preserving all images and content.
• Anti-AI-Slop — Curated distinctive styles that avoid generic AI aesthetics (bye-bye, purple gradients on white).
• Production Quality — Accessible, responsive, well-commented code you can customize.

Installation

For Claude Code Users

Copy the skill files to your Claude Code skills directory:

# Create the skill directory
mkdir -p ~/.claude/skills/frontend-slides/scripts

# Copy all files (or clone this repo directly)
cp SKILL.md STYLE_PRESETS.md viewport-base.css html-template.md animation-patterns.md ~/.claude/skills/frontend-slides/
cp scripts/extract-pptx.py ~/.claude/skills/frontend-slides/scripts/

Or clone directly:

git clone https://github.com/zarazhangrui/frontend-slides.git ~/.claude/skills/frontend-slides

Then use it by typing /frontend-slides in Claude Code.

Usage

Create a New Presentation

/frontend-slides

> "I want to create a pitch deck for my AI startup"

The skill will:

1. Ask about your content (slides, messages, images)
2. Ask about the feeling you want (impressed? excited? calm?)
3. Generate 3 visual style previews for you to compare
4. Create the full presentation in your chosen style
5. Open it in your browser

Convert a PowerPoint

/frontend-slides

> "Convert my presentation.pptx to a web slideshow"

The skill will:

1. Extract all text, images, and notes from your PPT
2. Show you the extracted content for confirmation
3. Let you pick a visual style
4. Generate an HTML presentation with all your original assets

Architecture

This skill uses progressive disclosure — the main SKILL.md is a concise map (~180 lines), with supporting files loaded on-demand only when needed:

File	Purpose	Loaded When
SKILL.md	Core workflow and rules	Always (skill invocation)
STYLE_PRESETS.md	12 curated visual presets	Phase 2 (style selection)
viewport-base.css	Mandatory responsive CSS	Phase 3 (generation)
html-template.md	HTML structure and JS features	Phase 3 (generation)
animation-patterns.md	CSS/JS animation reference	Phase 3 (generation)
scripts/extract-pptx.py	PPT content extraction	Phase 4 (conversion)

This design follows OpenAI's harness engineering principle: "give the agent a map, not a 1,000-page instruction manual."

Philosophy

This skill was born from the belief that:

1. You don't need to be a designer to make beautiful things. You just need to react to what you see.

2. Dependencies are debt. A single HTML file will work in 10 years. A React project from 2019? Good luck.

3. Generic is forgettable. Every presentation should feel custom-crafted, not template-generated.

4. Comments are kindness. Code should explain itself to future-you (or anyone else who opens it).

Requirements

• Claude Code CLI
• For PPT conversion: Python with python-pptx library
