border-inline-start-width

The border-inline-start-width CSS property defines the width of the logical inline-start border 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")}}, {{cssxref("border-right-width")}}, {{cssxref("border-bottom-width")}}, or {{cssxref("border-left-width")}} property depending on the values defined for {{cssxref("writing-mode")}}, {{cssxref("direction")}}, and {{cssxref("text-orientation")}}.
