This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Summary

The offset-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 toprightbottom, or left property depending on the values defined for writing-mode, direction, and text-orientation.

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