Drag & Drop File Upload UI
Build a drag-and-drop zone with onDragOver/onDrop events and visual feedback.
Welcome
In this lesson you will build a drag-and-drop file upload zone in React using native drag events and visual feedback to guide users.
Drag Event Overview
The browser fires drag events when files are dragged over elements. The key events are: `dragover` (file is over the element), `dragleave` (file leaves the element), and `drop` (file is released).
