mapper--picture hot area highlighting component official website_js object-oriented

A very interesting thing. We have all used image hotspots to link multiple slices, and we have also used the hover highlighting effect of links, but there is no way to achieve the highlighting effect of image hotspots (that is, hovering the mouse over a certain hotspot area the area is highlighted).

Mapper is such a small component that uses js drawing and css definition to implement such a useful function.
