padding-inline-start

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

Try it

Syntax

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

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

/* Global values */
padding-inline-start: inherit;
padding-inline-start: initial;
padding-inline-start: revert;
padding-inline-start: revert-layer;
padding-inline-start: unset;

Values

<length>: The size of the padding as a fixed value. Must be nonnegative.
<percentage>: The size of the padding as a percentage, relative to the inline size (width in a horizontal language, defined by writing-mode) of the containing block. Must be nonnegative.

Description

The padding-inline-start property is defined in the specification as taking the same values as the padding-top property. However, the physical property it maps to depends on the values set for writing-mode, direction, and text-orientation. Therefore, it could map to padding-bottom, padding-right, or padding-left.

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