offset-block-end

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

Theoffset-block-end CSS property defines the logical block end offset of an element, which maps to a physical offset 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.

/* <length> values */
offset-block-end: 3px;
offset-block-end: 2.4em;

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

/* Keyword value */
offset-block-end: auto;

/* Global values */
offset-block-end: inherit;
offset-block-end: initial;
offset-block-end: unset;

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

Inherited no
Percentages logical-height of containing block
Media visual
