The margin-inline-start CSS property defines the logical inline start 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.

Syntax

/* <length> values */
margin-inline-start: 10px;  /* An absolute length */
margin-inline-start: 1em;   /* relative to the text size */
margin-inline-start: 5%;    /* relative to the nearest block container's width */

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

/* Global values */
margin-inline-start: inherit;

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