padding

Summary

The padding property sets the padding space on all sides of an element. The padding area is the space between the content of the element and its border. Negative values are not allowed.

The padding property is a shorthand to avoid setting each side separately (padding-top, padding-right, padding-bottom, padding-left).

Syntax

/* Apply to all four sides */
padding: 1em;

/* vertical | horizontal */
padding: 5% 10%;

/* top | horizontal | bottom */
padding: 1em 2em 2em; 

/* top | right | bottom | left */
padding: 2px 1em 0 1em;

/* Global values */
padding: inherit;
padding: initial;
padding: unset;
