inset-block-start

The inset-block-start CSS property defines the logical block start offset 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.

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

Values: The inset-block-start property takes the same values as the top property.

Syntax example: inset-block-start: 3px;
