## What it does

This skill defines viewport rules across three form factors. Mobile layouts under 768px require touch targets of at least 44×44px and thumb-reachable navigation. Tablets between 768px and 1024px handle two-column master-detail views, while desktops above 1024px introduce hover states and persistent sidebars.

Stacking elements vertically is the default move. Moving controls into an entirely different container is prohibited because it disorients users; elements must stay within their original parent region. Sticky desktop toolbars switch to inline static elements or fixed bottom sheets on smaller screens.

Without a max-width container between 1280px and 1600px, interfaces stretch uncontrollably across 4K displays. The workflow enforces a mobile-first pattern where base styles target phones and `@media (min-width: ...)` queries layer on desktop features.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill responsive-paradigms -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill responsive-paradigms -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill responsive-paradigms -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dembrandt/dembrandt-skills responsive-paradigms
```

2. **Manually: put the files in place**
- File: `.github/skills/responsive-paradigms/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill responsive-paradigms -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dembrandt/dembrandt-skills --path skills/responsive-paradigms
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dembrandt/dembrandt-skills --skill responsive-paradigms -a opencode
```

### 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/dembrandt/dembrandt-skills/tree/HEAD/skills/responsive-paradigms/SKILL.md

## When to use it
- adapt a desktop dashboard for mobile viewports
- design touch-friendly navigation with tap targets of at least 44×44px
- reposition or hide secondary page sections across breakpoints
- constrain interface width on 2K and 4K ultra-wide monitors

## Example prompts
- How should this desktop sidebar behave on mobile screens?
- Design the mobile navigation and bottom bar for this layout.
- Which page sections should use display: none below the 768px breakpoint?

# Responsive Paradigms

Mobile, tablet, and desktop are fundamentally different interaction contexts. The input method, screen real estate, viewing distance, and session intent all differ. Responsive design is not the same layout at different widths — it is a different design decision at each breakpoint.

## The Three Paradigms

### Mobile (< 768px)
- **Input:** Touch — fingers, not a cursor. Tap targets ≥ 44×44px.
- **Navigation:** Bottom tab bar (thumb reachable) or hamburger drawer. Top navigation is hard to reach.
- **Session:** Often interrupted, task-focused, shorter. Show the most important thing first.
- **Content:** Single column. Vertical scroll only. No hover states.
- **Primary action:** Floating action button (FAB) or full-width button at the bottom of the screen.

### Tablet (768px–1024px)
- **Input:** Touch and sometimes keyboard/trackpad. Hybrid paradigm.
- **Navigation:** Can support a persistent sidebar at landscape orientation; collapses to drawer at portrait.
- **Content:** Two-column layouts work. Master-detail patterns (list + detail side by side) are natural.
- **Primary action:** Can be in-line with content, not necessarily floating.

### Desktop (> 1024px)
- **Input:** Mouse with hover states, keyboard shortcuts, precise clicking.
- **Navigation:** Persistent sidebar or top navigation. Both visible simultaneously.
- **Content:** Multi-column, dense information, toolbars, context menus.
- **Primary action:** In-context with content, supported by keyboard shortcuts for power users.
