border-inline-start

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

Syntax

border-inline-start: 1px;
border-inline-start: 2px dotted;
border-inline-start: medium dashed green;

border-inline-start can be used to set the values for one or more of border-inline-start-width, border-inline-start-style, and border-inline-start-color. The physical border to which it maps depends on the element's writing mode, directionality, and text orientation. It corresponds to the border-top, border-right, border-bottom, or border-left property depending on the values defined for writing-mode, direction, and text-orientation.

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