Requirements: - Dashed border container highlighting on dragenter / dragover. - Hidden input[type="file"] and secondary "Browse Local Files" button trigger. - File upload progress simulation card displaying filename and animated percentage bar. - Completion state turning progress green with checkmark. Return one HTML file with <style> and <script> tags.
How to build it, step by step
- 1
Bind dragover and dragleave listeners to toggle .is-dragover active styling.
- 2

Customisation tips
- Always call e.preventDefault() on drag events to stop the browser from opening the dropped file natively.
