The change in appearance of the border bottom from a full line to a triangle or a thin line when switching from position: relative to position: absolute is primarily due to how absolutely positioned elements are treated in the document flow. They don’t occupy space like statically or relatively positioned elements do, and their dimensions are often determined by their content or the dimensions of their absolutely positioned children. Therefore, if an absolutely positioned element has very little content or width, the border may visually collapse or appear differently than when the element is relatively positioned and part of the normal document flow.
