+# Mobile Integration Guide
+
+This document describes the mobile integration features added to Vue Fabric Editor as part of Issue #556.
+
+## Overview
+
+The mobile integration includes four main components:
+
+1. **Mobile Viewport Meta Tags** - Proper mobile browser configuration
+2. **Responsive CSS** - Adaptive layouts for different screen sizes
+3. **Touch Event Support** - Native touch gesture handling
+4. **Mobile Toolbar** - Touch-optimized UI component
+
+## Features
+
+### 1. Mobile Viewport Meta Tags
+
+Located in: `index.html`
+
+**Features:**
+- Responsive viewport configuration
+- PWA-ready meta tags
+- iOS home screen support
+- Theme color for light/dark mode
+- Format detection disabled (prevents auto-linking)
+- Safe area support for notched devices
+
+**Benefits:**
+- Better mobile browser experience
+- Can be added to home screen
+- Proper scaling on all devices
+- No unwanted auto-formatting
+
+### 2. Responsive CSS
+
+Located in: `src/styles/mobile-responsive.less`
+
+**Breakpoints:**
+- Small Mobile: < 480px
+- Mobile: 480px - 767px
+- Tablet: 768px - 1024px
+- Desktop: > 1024px
+
+**Features:**
+- Adaptive container widths
+- Responsive canvas sizing
+- Touch-friendly button sizes (44px minimum)
+- Landscape orientation support
+- Safe area insets for notched devices
+- Performance optimizations
+- Print styles
+
+**Usage:**
+Automatically applied via `src/styles/index.less` import.
+
+### 3. Touch Event Support
+
+Located in: `src/utils/touchEvents.ts` and `src/hooks/useTouchEvents.ts`
+
+**Supported Gestures:**
+- **Tap** - Single touch
+- **Double Tap** - Quick succession taps
+- **Long Press** - 500ms hold
+- **Swipe** - Left, right, up, down
+- **Pinch Zoom** - Two-finger scale
+- **Rotate** - Two-finger rotation
+
+**Usage Example:**
+
+```typescript
+import { useTouchEvents } from '@/hooks/useTouchEvents';
+
+const canvasRef = ref<HTMLElement | null>(null);
+
+useTouchEvents(canvasRef, {
+  onTap: (point) => {
+    console.log('Tapped at:', point.x, point.y);
+  },
+  onDoubleTap: (point) => {
+    console.log('Double tapped at:', point.x, point.y);
+  },
+  onLongPress: (point) => {
+    console.log('Long pressed at:', point.x, point.y);
+  },
+  onSwipe: (event) => {
+    console.log('Swiped:', event.direction, event.distance);
+  },
+  onPinch: (event) => {
+    console.log('Pinched:', event.scale);
+  },
+  onRotate: (event) => {
+    console.log('Rotated:', event.angle);
+  },
+});
+```
+
+**Direct Usage:**
+
+```typescript
+import TouchEventHandler from '@/utils/touchEvents';
+
+const element = document.getElementById('canvas');
+const handler = new TouchEventHandler(element);
+
+handler.on('tap', (point) => {
+  console.log('Tap at', point);
+});
+
+handler.on('pinch', (event) => {
+  console.log('Pinch scale', event.scale);
+});
+
+// Cleanup
+handler.destroy();
+```
+
+**Configuration:**
+
+```typescript
+handler.setConfig({
+  doubleTapDelay: 300,      // ms
+  longPressDelay: 500,      // ms
+  swipeThreshold: 50,       // px
+  swipeVelocityThreshold: 0.3, // px/ms
+  pinchThreshold: 10,       // px
+  rotateThreshold: 5,       // degrees
+});
+```
+
+### 4. Mobile Toolbar
+
+Located in: `src/components/MobileToolbar.vue`
+
+**Features:**
+- Floating action button (FAB)
+- Bottom sheet design
+- Touch-optimized buttons (44px minimum)
+- Smooth animations
+- Backdrop overlay
+- Safe area support
+- Landscape orientation support
+
+**Sections:**
+- **Quick Actions**: Undo, Redo, Delete, Copy
+- **Add Elements**: Text, Rectangle, Circle, Image
+- **Tools**: Zoom In, Zoom Out, Fit Screen, Reset
+- **Export**: PNG, JPG, SVG, Save
+
+**Usage Example:**
+
+```vue
+<template>
+  <div>
+    <MobileToolbar
+      :can-undo="canUndo"
+      :can-redo="canRedo"
+      :has-selection="hasSelection"
+      @undo="handleUndo"
+      @redo="handleRedo"
+      @delete="handleDelete"
+      @copy="handleCopy"
+      @add-text="handleAddText"
+      @add-shape="handleAddShape"
+      @add-image="handleAddImage"
+      @zoom-in="handleZoomIn"
+      @zoom-out="handleZoomOut"
+      @fit-screen="handleFitScreen"
+      @reset="handleReset"
+      @export="handleExport"
+      @save="handleSave"
+    />
+  </div>
+</template>
+
+<script setup lang="ts">
+import MobileToolbar from '@/components/MobileToolbar.vue';
+import { ref } from 'vue';
+
+const canUndo = ref(false);
+const canRedo = ref(false);
+const hasSelection = ref(false);
+
+const handleUndo = () => {
+  // Undo logic
+};
+
+const handleAddShape = (shape: string) => {
+  // Add shape logic
+};
+
+const handleExport = (format: string) => {
+  // Export logic
+};
+</script>
+```
+
+**Props:**
+- `canUndo` (boolean) - Enable/disable undo button
+- `canRedo` (boolean) - Enable/disable redo button
+- `hasSelection` (boolean) - Enable/disable selection-dependent buttons
+
+**Events:**
+- `@undo` - Undo action
+- `@redo` - Redo action
+- `@delete` - Delete selection
+- `@copy` - Copy selection
+- `@add-text` - Add text element
+- `@add-shape` - Add shape (rect, circle)
+- `@add-image` - Add image
+- `@zoom-in` - Zoom in
+- `@zoom-out` - Zoom out
+- `@fit-screen` - Fit to screen
+- `@reset` - Reset canvas

+
+## Browser Support
+

+
+## Testing
+
+### Mobile Testing Checklist
+
+- [ ] Viewport scales correctly on all devices
+- [ ] Touch gestures work (tap, swipe, pinch, rotate)
+- [ ] Toolbar appears only on mobile (< 768px)
+- [ ] Buttons are touch-friendly (44px minimum)
+- [ ] Landscape orientation works
+- [ ] Safe area insets respected on notched devices
+- [ ] No zoom on input focus
+- [ ] Smooth scrolling with momentum
+- [ ] Export functions work on mobile
+- [ ] Performance is acceptable
+
+### Testing Tools
+
+1. **Chrome DevTools**: Device emulation
+2. **Firefox Responsive Design Mode**: Device testing
+3. **BrowserStack**: Real device testing
+4. **Physical Devices**: iOS and Android
+
+## Performance Considerations
+
+1. **Reduced Animations**: Animations are shortened on mobile (0.2s)
+2. **Hardware Acceleration**: `transform: translateZ(0)` for canvas
+3. **Passive Event Listeners**: Used where possible
+4. **Touch Action**: `touch-action: none` prevents default behaviors
+5. **Debouncing**: Resize events are debounced
+
+## Accessibility
+
+1. **Touch Target Size**: Minimum 44x44px
+2. **Focus Indicators**: 2px outline on focus
+3. **ARIA Labels**: Added to toolbar buttons
+4. **Contrast**: Improved for mobile readability
+5. **Line Height**: 1.6 for better readability
+
+## Future Enhancements
+
+Potential improvements for future PRs:
+
+1. **Gesture Customization**: Allow users to customize gestures
+2. **Haptic Feedback**: Vibration on touch interactions
+3. **Offline Support**: PWA with service worker
+4. **Mobile Templates**: Pre-made mobile-optimized templates
+5. **Voice Commands**: Voice-based editing
+6. **AR Preview**: View designs in AR on mobile
+
+## Contributing
+
+When adding mobile features:
+
+1. Test on real devices
+2. Follow touch target size guidelines (44px minimum)
+3. Use passive event listeners when possible
+4. Consider landscape orientation
+5. Support safe area insets
+6. Add to this documentation
+
+## License
+
+Same as the main project (MIT).
