Constituent properties

This property is a shorthand for the following CSS properties:


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: revert-layer;
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.


The border-block-end is specified with one or more of the following, in any order:


The width of the border. See border-width.


The line style of the border. See border-style.


The color of the border. See color.
