border-inline

The border-inline CSS property is a shorthand property for setting the individual logical inline border property values in a single place in the style sheet.

The physical borders to which border-inline maps depends on the element's writing mode, directionality, and text orientation. It corresponds to the border-top and border-bottom or border-right, and border-left properties, depending on the values defined for writing-mode, direction, and text-orientation.

The borders in the other dimension can be set with border-block, which sets border-block-start, and border-block-end.
