padding-block CSS property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

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.

Try it

padding-block: 10px 20px;
writing-mode: horizontal-tb;

padding-block: 20px 40px;
writing-mode: vertical-rl;

padding-block: 5% 10%;
writing-mode: horizontal-tb;

padding-block: 2em 4em;
writing-mode: vertical-lr;

<section id="default-example">
  <div class="transition-all" id="example-element">
    <div class="box">
      Far out in the uncharted backwaters of the unfashionable end of the
      western spiral arm of the Galaxy lies a small unregarded yellow sun.
    </div>
  </div>
</section>

#example-element {
  border: 10px solid #ffc129;
  overflow: hidden;
  text-align: left;
}

.box {
  border: dashed 1px;
  unicode-bidi: bidi-override;
}

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

css
/* <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: revert-layer;
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.

Values

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

Description

The padding values specified by padding-block can be equivalent to the padding-top and padding-bottom properties or the padding-right and padding-left properties, depending on the values defined for writing-mode, direction, and text-orientation.
