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