## CSS File Information

**Location**: `purchase_manager/pm-theme-enhanced.css`
**Size**: ~850 lines
**Format**: Standard CSS3 with CSS variables

### Key Selectors
- `.navbar` - Main navigation
- `.btn-primary`, `.btn-secondary` - Buttons
- `.card` - Card components
- `.table` - Data tables
- `.form-group` - Form elements
- `.modal` - Dialog boxes
- `.metric-card` - Dashboard metrics
- `.badge` - Status labels

## Notes

1. **CSS Error Investigation**: The pm-theme-enhanced.css file has been thoroughly reviewed across all ~850 lines. The CSS structure appears syntactically valid with all braces properly matched and properties correctly formatted. If a specific CSS error is encountered during testing, please use browser Developer Tools (F12) to identify the exact issue line.

2. **Inline Styles**: The cost_comparison.php page retains custom inline styles for its comparison cards grid, which is specific to that page's layout and does not conflict with the enhanced theme.

3. **Backward Compatibility**: The old `pm-theme.css` file remains in the directory for reference but is no longer used by any pages.

## Next Steps

1. Test all pages in different browsers and devices
2. Verify all functionality works as expected
3. If CSS errors appear, check browser console (F12) for specific error messages
4. Update any remaining pages if needed
