var left=10;//The left position of the box
var top= 20;//Position

on the box. I don’t know what the specific use of these two definitions is?

It seems that changing the size has no effect on the effect.

Principle:
pixelTop and offsetTop are different, pixelTop is actually style. The numeric form of top. And offsetTop is the actual offset of the object.
At the beginning, the top of this fk object is undefined, so the pixelTop is 0, and the offsetTop is not 0 due to the existence of the body's margin, which is actually the value of the margin.
