inset-inline

The inset-inline CSS property defines the logical start and end offsets of an element in the inline direction, which maps 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.

This inset property has no effect on non-positioned elements.
