Then place a div in the body element, we need to implement other content into this div, as shown in the figure below
Next we define the style for the div, mainly the width, height and border, to make its area more obvious, as shown in the figure below, and place the image ready for dragging and dropping
Next we need to implement the drag and drop event function, as shown in the figure below. What needs to be implemented here are the three functions allowDrop, drag and drop, as shown in the figure below
Then we run the interface program, and you will see an empty drop box and a picture on the page, as shown below

Using ID selectors is not inherently bad in CSS, but should be used with caution. 1) ID selector is suitable for unique elements or JavaScript hooks. 2) For general styles, class selectors should be used as they are more flexible and maintainable.
