border-inline-start-style

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

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