padding-block-end CSS property

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

Try it

padding-block-end: 20px;
writing-mode: horizontal-tb;
padding-block-end: 20px;
writing-mode: vertical-rl;
padding-block-end: 5em;
writing-mode: horizontal-tb;
padding-block-end: 5em;
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;
}

Syntax

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

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

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

Values

<length>

The size of the padding as a fixed value. Must be non-negative.

<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 non-negative.

Description

The padding-block-end property takes the same values as physical padding properties such as padding-top. However, it can be equivalent to padding-bottom, padding-top, padding-left, or padding-right depending on the values set for writing-mode, direction, and text-orientation.

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