Making elements draggable with the HTML5 `draggable` attribute.
Article Introduction：To implement the draggable function of web page elements, using HTML5's draggable attribute is a direct method. The specific steps are as follows: 1. Add draggable="true" to the target element to enable the drag function; 2.

Enhance visual feedback through CSS, such as hover and active state to adjust transparency; 4. Pay attention to compatibility and details, such as poor mobile support or browser default behavior to prevent dragging, you need to use e.preventDefault() to handle it; 5. It is recommended to use professional libraries such as ReactD in complex scenarios.
