The padding-block CSS 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.

/* <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: unset;

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.

The values can be set individually as padding-block-start and padding-block-end. The inline direction property is padding-inline which sets padding-inline-start, and padding-inline-end.
