padding-block-start

The padding-block-start CSS property defines the logical block start padding of an element, which maps to a physical padding depending on the element's writing mode, directionality, and text orientation.

Syntax

/* <length> values */
padding-block-start: 10px;      /* An absolute length */
padding-block-start: 1em;       /* A length relative to the text size */

/* <percentage> value */
padding-block-start: 5%;        /* A padding relative to the block container's width */

/* Global values */
padding-block-start: inherit;
padding-block-start: initial;
padding-block-start: unset;

Values

The padding-block-start property takes the same values as the padding-left property.

Description

This property corresponds to the padding-top, padding-right, padding-bottom, or padding-left property depending on the values defined for writing-mode, direction, and text-orientation.

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