## What it does

The skill walks an agent through installing Tailwind v4 in a Capacitor project. It knows v4 config lives in CSS: `@import "tailwindcss"`, `@theme`, `@utility`, `@custom-variant`, `@source`, `@plugin`. Vite builds get `tailwindcss` plus `@tailwindcss/vite`; Angular, webpack and Next go through `@tailwindcss/postcss`. Coming from v3, it points at `npx @tailwindcss/upgrade` and lists what gets renamed afterwards.

A second part covers mobile patterns. Safe-area utilities are built on `env(safe-area-inset-*)`, `ios:` and `android:` variants key off a root class (`plt-ios`/`plt-android`), dark mode is class-based, and `pointer-coarse:` sizes touch targets. It also flags the traps: dynamic class names like `bg-${color}-500` are never generated, and `hover:` in v4 only fires where a real pointer exists.

The hard limit is the WebView. v4 needs Safari 16.4+ and Chrome 111+, while Capacitor 8 supports iOS 15+ and Capacitor 9 iOS 16+. On iOS 15.x–16.3 devices the styles render wrong, so the skill tells the agent to ask whether to stay on Tailwind 3.4 or raise the minimum OS. It will not ship v4 quietly. Konsta UI components, Ionic theming, system bars and keyboard overlap live in separate skills.

## Requirements
- Works with: Chrome

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill tailwind-capacitor -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill tailwind-capacitor -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill tailwind-capacitor -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Cap-go/capgo-skills tailwind-capacitor
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill tailwind-capacitor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Cap-go/capgo-skills --path skills/tailwind-capacitor
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill tailwind-capacitor -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/Cap-go/capgo-skills/tree/HEAD/skills/tailwind-capacitor/SKILL.md

## When to use it
- install Tailwind v4 in a Vite or PostCSS Capacitor project
- fix styles that vanish after moving from v3 to v4
- debug broken colors and gradients on older iPhones
- pad layouts around the notch and home indicator
- split styling between iOS and Android with one root class

## Example prompts
- set up Tailwind v4 in this Capacitor project with a CSS-first config
- styles stopped applying after the v4 upgrade — find out why and fix it
- add safe-area utilities and an ios: variant for the top bar

description: Sets up and uses Tailwind CSS v4 in Capacitor apps - CSS-first config (`@import "tailwindcss"`, `@theme`, `@utility`, `@custom-variant`, `@source`, `@plugin`), `@tailwindcss/vite` / `@tailwindcss/postcss`, upgrading from v3 `tailwind.config.js` with `npx @tailwindcss/upgrade`, WebView browser floor (Safari 16.4+ / Chrome 111+ vs Capacitor iOS 15/16 targets), safe-area utilities built on `env(safe-area-inset-*)`, platform variants (`ios:`/`android:` via a root class), class-based dark mode, `pointer-coarse:` touch targets, and hover-on-touch behavior. Use when installing Tailwind in a Capacitor project, styles do not apply after upgrading to v4, colors look wrong on older iPhones, or building mobile layouts with Tailwind. Do not use for Konsta UI components (konsta-ui), Ionic theming (ionic-design), native system bar / edge-to-edge config (safe-area-handling), or keyboard overlap (capacitor-keyboard).

# Tailwind CSS in Capacitor Apps

## When to Use

TRIGGER when:
- Adding Tailwind to a Capacitor app (Vite, Angular, Next static export, etc.)
- Upgrading Tailwind v3 -> v4, or a v4 install produces no styles
- `tailwind.config.js` edits have no effect (v4 is CSS-first)
- Colors / gradients broken or transparent on older iOS devices
- Safe-area, dark mode, platform-specific, or touch-target utilities

Do not use:
- Konsta UI setup/components: `konsta-ui`
- Ionic components and `--ion-*` variables: `ionic-design`
- SystemBars / Android edge-to-edge / status bar plugin: `safe-area-handling`
- Inputs hidden by keyboard: `capacitor-keyboard`
- Adding Capacitor to a framework: `framework-to-capacitor`

## Version facts (October 2026)

- `tailwindcss` 4.x is `latest` (4.3.x); 3.4.x on `v3-lts`.
- v4 is configured in CSS. `tailwind.config.js` is not read unless you add `@config "./tailwind.config.js";`.
- v4 targets **Safari 16.4+, Chrome 111+, Firefox 128+** (uses `@property`, `color-mix()`, cascade layers, oklch).
- Capacitor 8 supports iOS 15+, Capacitor 9 iOS 16+. WKWebView = the device's Safari version. **Devices on iOS 15.x - 16.3 render v4 styles incorrectly.** Android System WebView auto-updates, so Chrome 111+ is usually met (Capacitor 9 minSdk 26).

Decision: if the iOS deployment target (or real user base) includes iOS < 16.4, ask the user: stay on Tailwind 3.4, or raise the minimum OS. Do not silently ship v4.
