The border-inline-start-color CSS property defines the color of the logical inline start 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.
border-inline-start-color: red; border-inline-start-color: #ee4141;
Related properties are border-block-start-color, border-block-end-color, and border-inline-end-color, which define the other border colors of the element.
