margin-block-end: 1em;       /* A length relative to the text size */

The margin-block-end property takes the same values as the margin-left property.

Formal syntax

<a href="css/margin-left" title="&lt;length&gt; | &lt;percentage&gt; | auto"><'margin-left'></a>


The margin-block-end CSS property defines the logical block end margin of an element, which maps to a physical margin depending on the element's writing mode, directionality, and text orientation. It corresponds to the margin-topmargin-rightmargin-bottom, or margin-left property depending on the values defined for writing-mode, direction, and text-orientation.

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