padding

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

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

This property is a shorthand for the following CSS properties:

• padding-bottom
• padding-left
• padding-right
• padding-top

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

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

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

/* top | right | bottom | left */
padding: 5px 1em 0 2em;

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

The padding property may be specified using one, two, three, or four values. Each value is a <length> or a <percentage>. Negative values are invalid.

• When one value is specified, it applies the same padding to all four sides.
• When two values are specified, the first padding applies to the top and bottom, the second to the left and right.
• When three values are specified, the first padding applies to the top, the second to the right and left, the third to the bottom.
• When four values are specified, the paddings apply to the top, right, bottom, and left in that order (clockwise).

<length>

The size of the padding as a fixed value.

<percentage>

The size of the padding as a percentage, relative to the width of the containing block.

[ <length> | <percentage> ]{1,4}

HTML

<h4>This element has moderate padding.</h4>
<h3>The padding is huge in this element!</h3>

CSS

h4 {
  background-color: lime;
  padding: 20px 50px;
}

h3 {
  background-color: cyan;
  padding: 110px 50px 50px 110px;
}

Result

padding: 5%;                /* All sides: 5% padding */

padding: 10px;              /* All sides: 10px padding */

padding: 10px 20px;         /* top and bottom: 10px padding */
                            /* left and right: 20px padding */

padding: 10px 3% 20px;      /* top:            10px padding */
                            /* left and right: 3% padding   */
                            /* bottom:         20px padding */

padding: 1em 3px 30px 5px;  /* top:    1em padding  */
                            /* right:  3px padding  */
                            /* bottom: 30px padding */
                            /* left:   5px padding  */
