the following picture circle, I want to add a DIV or SPAN tag that can be edited, rotated, zoomed in and out, and at the same time, such as the icon in the shape of a landmark in the following picture, you can move and edit a point like editing the Bessel line, how to write this in JS+CSS, and how to think about it. In addition, if the final HTML+CSS generated after editing the style in this way does not want to have editing points, how to do it? thank you, gods.
