`margin-inline-end` CSS property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It's been available across browsers since September 2021.

The margin-inline-end CSS property defines the logical inline end margin of an element, which maps to a physical margin depending on the element's writing mode, directionality, and text orientation. In other words, it corresponds to the margin-top, margin-right, margin-bottom or margin-left property depending on the values defined for writing-mode, direction, and text-orientation.

Try it

margin-inline-end: 20px;
writing-mode: horizontal-tb;

margin-inline-end: 20px;
writing-mode: vertical-rl;

margin-inline-end: 20%;
writing-mode: horizontal-tb;
direction: rtl;

<section id="default-example">
  <div id="container">
    <div class="col">One</div>
    <div class="col transition-all" id="example-element">Two</div>
    <div class="col">Three</div>
  </div>
</section>

#container {
  width: 300px;
  height: 200px;
  display: flex;
  align-content: flex-start;
  justify-content: flex-start;
}

.col {
  width: 33.33%;
  border: solid #ce7777 10px;
  background-color: #2b3a55;
  color: white;
  flex-shrink: 0;
}

#example-element {
  border: solid 10px #ffbf00;
  background-color: #2b3a55;
  unicode-bidi: bidi-override;
}

Syntax

/* <length> values */
margin-inline-end: 10px; /* An absolute length */
margin-inline-end: 1em; /* relative to the text size */
margin-inline-end: 5%; /* relative to the nearest block container's width */
margin-inline-end: anchor-size(height);
margin-inline-end: calc(anchor-size(--my-anchor self-inline, 25px) / 5);

/* Keyword values */
margin-inline-end: auto;

/* Global values */
margin-inline-end: inherit;
margin-inline-end: initial;
margin-inline-end: revert;
margin-inline-end: revert-layer;
margin-inline-end: unset;

It relates to margin-block-start, margin-block-end, and margin-inline-start, which define the other margins of the element.
