border-block-end

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

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

border-block-end: 1px;
border-block-end: 2px dotted;
border-block-end: medium dashed blue;

border-block-end can be used to set the values for one or more of border-block-end-width, border-block-end-style, and border-block-end-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-inline-start, and border-inline-end, which define the other borders of the element.

Computed value as each of the properties of the shorthand:

Canonical order the unique non-ambiguous order defined by the formal grammar
