Issues Found and Fixed
1. Missing Interactive Styling
Problem: The upload box didn't look clickable or interactive.
Fixed:
- Added cursor: pointer to make it clear the area is clickable
- Added display: block for full clickability
- Added background color for better visibility
- Added smooth transitions for better UX
2. No Visual Feedback
Problem: When a file was selected, users had no confirmation.
Fixed: - Added JavaScript to detect file selection - Shows selected filename in a green badge - Changes upload box color to green (success state) - Updates text to "✅ Photo Selected"
3. No Hover Effects
Problem: No indication that the upload area is interactive.
Fixed: - Added purple border and background on hover - Smooth color transitions for professional feel
4. Drag & Drop Support
Bonus: Added full drag-and-drop functionality for better UX.
5. Image Preview
Enhancement: Display the selected photo immediately before submission.
