padding CSS property

The padding CSS shorthand property sets the padding area on all four sides of an element at once.

Try it

padding: 1em;
padding: 10% 0;
padding: 10px 50px 20px;
padding: 10px 50px 30px 0;
padding: 0;
<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;
}

An element's padding area is the space between its content and its border.

Note: Padding creates extra space within an element. In contrast, margin creates extra space around an element.

Constituent properties

This property is a shorthand for the following CSS properties:
