border-inline-width

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

The border width in the other dimension can be set with {{cssxref("border-block-width")}}, which sets {{cssxref("border-block-start-width")}}, and {{cssxref("border-block-end-width")}}.
