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

Constituent properties

This property is a shorthand for the following CSS properties:


/* <length> values */
padding-block: 10px 20px;  /* An absolute length */
padding-block: 1em 2em;   /* relative to the text size */
padding-block: 10px; /* sets both start and end values */

/* <percentage> values */
padding-block: 5% 2%; /* relative to the nearest block container's width */

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

The padding-block property may be specified with one or two values. If one value is given, it is used as the value for both padding-block-start and padding-block-end. If two values are given, the first is used for padding-block-start and the second for padding-block-end.


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


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