border-block-end-width

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The border-block-end-width CSS property defines the width of the logical block-end 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 border-top-width, border-right-width, border-bottom-width, or border-left-width property depending on the values defined for writing-mode, direction, and text-orientation.

Syntax

/* <'border-width'> values */
border-block-end-width: 5px;
border-block-end-width: thick;

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