border-inline-end-color

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

Syntax

border-inline-end-color: rebeccapurple;
border-inline-end-color: #663399;

Related properties are border-block-start-color, border-block-end-color, and border-inline-start-color, which define the other border colors of the element.
