inset-inline-end

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

Note: Prior to Firefox 63 this property was implemented as offset-inline-end. Firefox 63 updated the name of this property to match a change to the specification.

/* <length> values */
inset-inline-end: 3px;
inset-inline-end: 2.4em;

/* <percentage>s of the width or height of the containing block */
inset-inline-end: 10%;

/* Keyword value */
inset-inline-end: auto;

/* Global values */
inset-inline-end: inherit;
inset-inline-end: initial;
inset-inline-end: unset;

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