Description

This Drag-and-Drop project offers an interactive interface for moving list items between two sections. Users can drag items from a source container and drop them into a target container, creating a dynamic way to organize and rearrange content. Built with HTML, CSS, and JavaScript, this project is perfect for applications where users need to customize layouts, such as to-do lists or content organizers. The drag-and-drop functionality is intuitive, making it accessible for users and enhancing engagement with its smooth, responsive interactions.

This project demonstrates how JavaScript event listeners manage the drag-and-drop process, ensuring that each item remains draggable and returns visual feedback to the user. The code handles both the drag and drop events, enabling easy content transfer back and forth between sections. This type of user interface is common in modern applications and improves user experience by allowing direct manipulation of content.
