+# Phase 2 Implementation Summary - Divider Block Migration
+
+## Overview
+Successfully migrated the divider block to the new block handler architecture as a proof of concept.
+
+## Changes Made
+
+### 1. Created Block Handler
+- **File**: `blocks/content/divider.block.ts`
+- Implemented `DividerBlockHandler` class extending `BaseBlockHandler`
+- Extracted divider rendering logic from `dees-wysiwyg-block.ts`
+- Extracted divider setup logic (event handlers)
+- Extracted divider-specific styles
+
+### 2. Registration System
+- **File**: `wysiwyg.blockregistration.ts`
+- Created registration module that registers all block handlers
+- Currently registers only the divider handler
+- Includes placeholders for future block types
+
+### 3. Updated Block Component
+- **File**: `dees-wysiwyg-block.ts`
+- Added import for BlockRegistry and handler types
+- Modified `renderBlockContent()` to check registry first
+- Modified `firstUpdated()` to use registry for setup
+- Added `injectHandlerStyles()` method to inject handler styles dynamically
+- Removed hardcoded divider rendering logic
+- Removed hardcoded divider styles
+- Removed `setupDividerBlock()` method
+
+### 4. Updated Exports
+- **File**: `blocks/index.ts`
+- Exported `DividerBlockHandler` class
+
+## Key Features Preserved
+✅ Visual appearance with gradient and icon
+✅ Click to select behavior  
+✅ Keyboard navigation support (Tab, Arrow keys)
+✅ Deletion with backspace/delete
+✅ Focus/blur handling
+✅ Proper styling for selected state
+
+## Architecture Benefits
+1. **Modularity**: Each block type is now self-contained
+2. **Maintainability**: Block-specific logic is isolated
+3. **Extensibility**: Easy to add new block types
+4. **Type Safety**: Proper TypeScript interfaces
+5. **Code Reuse**: Common functionality in BaseBlockHandler
+
+## Next Steps
+To migrate other block types, follow this pattern:
+1. Create handler file in appropriate folder (text/, media/, content/)
+2. Extract render logic, setup logic, and styles
+3. Register in `wysiwyg.blockregistration.ts`
+4. Remove hardcoded logic from `dees-wysiwyg-block.ts`
+5. Export from `blocks/index.ts`
+
+## Testing
+- Project builds successfully without errors
+- Existing tests pass
+- Divider blocks render and function identically to before
