inset

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

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

/* <length> values */
inset: 3px 10px 3px 10px;
inset: 2.4em 3em 3em 3em;
inset: 10px; /* value applied to all edges */

/* <percentage>s of the width or height of the containing block */
inset: 10% 5% 5% 5%;

/* Keyword value */
inset: auto;

/* Global values */
inset: inherit;
inset: initial;
inset: unset;
