inset-block-end - CSS: Cascading Style Sheets 编辑

The inset-block-end CSS property defines the logical block end 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.

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

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

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

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