border-inline

The border-inline CSS property is a shorthand property for setting the individual logical inline border property values in a single place in the style sheet.

Try it

border-inline: solid;
writing-mode: horizontal-tb;

border-inline: dashed red;
writing-mode: vertical-rl;

border-inline: 1rem solid;
writing-mode: horizontal-tb;
direction: rtl;

<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;
}

The physical borders to which border-inline maps depends on the element's writing mode, directionality, and text orientation. It corresponds to the border-top and border-bottom or border-right, and border-left properties, depending on the values defined for writing-mode, direction, and text-orientation.

The borders in the other dimension can be set with border-block, which sets border-block-start, and border-block-end.
