The border-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.

Constituent properties

This property is a shorthand for the following CSS properties:

border-block-end-color border-block-end-style border-block-end-width

Syntax

border-block-end: 1px; border-block-end: 2px dotted; border-block-end: medium dashed blue;  /* Global values */ border-block-end: inherit; border-block-end: initial; border-block-end: revert; border-block-end: unset; 

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.

<'border-width'>

The width of the border. See border-width.

<'border-style'>
