Description  

The padding-block-start CSS property defines the logical block start padding of an element, which maps to a physical padding depending on the element's writing mode, directionality, and text orientation. It corresponds to the padding-toppadding-rightpadding-bottom, or padding-left property depending on the values defined for writing-mode, direction, and text-orientation.

It relates to padding-block-end, padding-inline-start, and padding-inline-end, which define the other paddings of the element.
