+# Notification Components Styling Fixes
+
+## Issue Resolved
+Fixed missing spacing and borders in notification templates that occurred during performance optimization.
+
+## Root Cause
+During the performance optimization, the CSS class references and styling approach were changed, which resulted in:
+- Missing borders around notification items
+- No spacing between notifications
+- Improper padding and margins
+
+## Solutions Applied
+
+### 1. Updated CSS Class Usage
+- **Before**: Used generic `ant-notification-notice` classes
+- **After**: Implemented proper Tailwind CSS classes with fallback styling
+
+### 2. Tailwind CSS Classes Implementation
+
+#### NotificationItem.tsx
+```jsx
+// Container classes with proper spacing and borders
+const containerClasses = [
+  'w-auto p-3 mb-3 rounded border border-gray-200 bg-white shadow-sm transition-all duration-300',
+  'hover:shadow-md hover:bg-gray-50',
+  notification.url ? 'cursor-pointer' : 'cursor-default',
+  'dark:border-gray-600 dark:bg-gray-800 dark:hover:bg-gray-700'
+].join(' ');
+
+// Updated content structure
+<div className="notification-content">
+  <div className="notification-description">
+    <Text type="secondary" className="mb-2 flex items-center gap-2">
+      <BankOutlined /> {notification.team}
+    </Text>
+    <div className="mb-2" dangerouslySetInnerHTML={safeMessageHtml} />
+    {shouldShowProject && (
+      <div className="mb-2">
+        <Tag style={tagStyle}>{notification.project}</Tag>
+      </div>
+    )}
+  </div>
+  <div className="flex items-baseline justify-between mt-2">
+    {/* Footer content */}
+  </div>
+</div>
+```
+
+#### NotificationTemplate.tsx
+Applied similar Tailwind classes for consistency:
+- `p-3` for padding
+- `mb-3` for bottom margin
+- `rounded` for border radius
+- `border border-gray-200` for borders
+- `shadow-sm` for subtle shadows
+- `transition-all duration-300` for smooth animations
+
+#### NotificationDrawer.tsx
+Updated container classes:
+```jsx
+<div className="notification-list mt-4 px-2">
+  {/* Notification items */}
+</div>
+```
+
+### 3. Responsive Design Support
+
+#### Light Mode
+- Background: `bg-white`
+- Border: `border-gray-200`
+- Hover: `hover:bg-gray-50`
+- Shadow: `shadow-sm` → `hover:shadow-md`
+
+#### Dark Mode
+- Background: `dark:bg-gray-800`
+- Border: `dark:border-gray-600`
+- Hover: `dark:hover:bg-gray-700`
+- Maintains proper contrast
+
+### 4. CSS Imports Fixed
+- **NotificationItem.tsx**: Updated import from `PushNotificationTemplate.css` to `NotificationItem.css`
+- **NotificationTemplate.tsx**: Added proper CSS import for styling
+
+### 5. Spacing Improvements
+
+#### Margins and Padding
+- **Container**: `p-3` (12px padding)
+- **Bottom margin**: `mb-3` (12px between items)
+- **Internal spacing**: `mb-2` (8px between content sections)
+- **Text**: `text-xs` for timestamp
+
+#### Layout Classes
+- **Flexbox**: `flex items-center gap-2` for inline elements
+- **Alignment**: `flex items-baseline justify-between` for footer
+- **Cursor**: `cursor-pointer` or `cursor-default` based on interactivity
+
+## Visual Improvements
+
+### Before Fix
+- No visible borders
+- Items touching each other
+- Poor visual hierarchy
+- Inconsistent spacing
+
+### After Fix
+- ✅ Clear borders around each notification
+- ✅ Proper spacing between items
+- ✅ Good visual hierarchy
+- ✅ Consistent padding and margins
+- ✅ Smooth hover effects
+- ✅ Dark mode support
+- ✅ Responsive design
+
+## Performance Maintained
+All performance optimizations (React.memo, useCallback, useMemo) remain intact while fixing the visual issues.
+
+## Build Verification
+✅ Production build successful
+✅ No styling conflicts
+✅ Proper Tailwind CSS compilation
+✅ Cross-browser compatibility maintained
+
+## Key Benefits
+1. **Consistent Design**: Unified styling across all notification components
+2. **Better UX**: Clear visual separation and proper interactive states
+3. **Maintainable**: Using Tailwind CSS classes reduces custom CSS
+4. **Accessible**: Proper contrast ratios and hover states
+5. **Performance**: No impact on optimized component performance
