Description  

The border-block-end CSS property is a shorthand property for setting the individual logical block end border property values in a single place in the style sheet. border-block-end can be used to set the values for one or more of: border-block-end-width, border-block-end-style, border-block-end-color. It maps to a physical border depending on the element's writing mode, directionality, and text orientation. It corresponds to the border-topborder-rightborder-bottom, or border-left property depending on the values defined for writing-mode, direction, and text-orientation.

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