PositionUnderflow class
A position unit that represents the amount of empty space when content is smaller than viewport.
This position unit returns the positive difference between viewport size and content size. It returns 0 if the content exceeds or matches the viewport. This is useful for centering content or positioning elements when there's extra space.
