## What it does

This skill guides layout generation through a five-step container-in-container workflow. An outer centered container controls global page width, bounded by visible vertical guide lines and corner markers.

Inner containers sit inset from the perimeter with dedicated padding, custom background colors, and rounded borders. This hierarchy separates hero blocks, feature lists, social proof, and call-to-action sections without piling up heavy cards.

Layout guardrails prevent common design mistakes here. Over-nesting cards will quickly box in the layout, and thick boundary lines risk hurting text readability.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill nested-container-frames -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill nested-container-frames -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill nested-container-frames -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MengTo/Skills nested-container-frames
```

2. **Manually: put the files in place**
- File: `.github/skills/nested-container-frames/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill nested-container-frames -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MengTo/Skills --path agent-skills/web-design/nested-container-frames
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/nested-container-frames/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MengTo/Skills --skill nested-container-frames -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- structure web layouts with nested container frames
- add visible boundary lines and corner markers to outer bounds
- separate page modules without stacking heavy card components
- maintain consistent inset padding and border radii across frame levels

## Example prompts
- Build a hero section and feature grid using nested-container-frames
- Structure this landing page with outer boundary lines and inset frames via nested-container-frames
- Refactor our page layout to use nested-container-frames instead of heavy card blocks

description: "Create a container-in-container layout system using nested frames. Use an outer centered container with visible vertical boundary lines and corner markers. Inside, place inner containers inset from the edges, each with its own background and rounded frame. Technique: outer container defines global bounds, inner containers use padding to create inset spacing, layered frames (border + background) to separate levels, and consistent spacing between outer frame and inner blocks."

# Nested Container Frames Skill

## Use When
- A layout needs a container-in-container system with visible outer bounds, inset inner frames, and layered page structure.

## Workflow
1. Define an outer centered container that controls the global page width.
2. Add visible vertical boundary lines and small corner markers to establish the frame.
3. Place inner containers inset from the outer edges using consistent padding.
4. Give each inner level its own background, border, radius, and spacing rhythm.
5. Use the frame hierarchy to separate hero, feature, proof, and CTA modules without adding heavy cards.

## Guardrails
- Do not nest cards inside cards until the layout feels boxed in.
- Do not let frame lines overpower content readability.
