On the difference between margin and padding
Padding is the angle of the parent view that describes the problem, and is the distance between itself and the edge of its parent control. Margin is to stand in their own perspective to describe the problem, and the distance from the side of a component, if there is only one view at the same level, then its effect is basically the same as padding.
