border-block-end

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨January 2020⁩.

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.

Try it

border-block-end: solid;
writing-mode: horizontal-tb;

border-block-end: dashed red;
writing-mode: vertical-rl;

border-block-end: 1rem solid;
writing-mode: horizontal-tb;

border-block-end: thick double #32a1ce;
writing-mode: vertical-lr;

<section class="default-example" id="default-example">
  <div class="transition-all" id="example-element">
    This is a box with a border around it.
  </div>
</section>

#example-element {
  background-color: #eeeeee;
  color: darkmagenta;
  padding: 0.75em;
  width: 80%;
  height: 100px;
  unicode-bidi: bidi-override;
}

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

css
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.

<'border-width'>
