CSS PADDING

This is a shorthand property which allows an author to specify ‘padding-top’, ‘padding-right’, ‘padding-bottom’, and ‘padding-left’ properties using a single property and value notation (the values are given in this order separated by spaces.) If one or more of the values are not present, the value for a missing side is taken from the opposite side that is present. If only one value is listed, it applies to all sides. The rendered surface of the padding area is taken from the ‘background’ property.

Example

body {
  padding: 5px 5px 2px 25px
}
1
<body style="padding: 5px 5px 2px 25px">some content</body>

[length]: Refers to either an absolute measurement or a relative measurement based on the current element’s font size.
[percentage]: Refers to a percentage of the width of the current element’s containing block.
