Instructions

The margin and padding shorthand properties interpret values in the same way:

  • One value: All four sides are set uniformly.
  • Two values: The first value sets the top and bottom; the second value sets right and left.
  • Three values: The first value sets the top; second value sets both the right and left sides; and the third value sets the bottom.
  • Four values: Each value sets the top, right, bottom and left, respectively.

First let's start with the syntax:

  1. selector {
    padding: AllSides;
    }
    selector {
    padding: TopAndBottom RightAndLeft;
    }
    selector {
    padding: Top RightAndLeft Bottom;
    }
    selector {
    padding: Top Right Bottom Left;
    }
    The initial value for each margin and padding property is 0.
  2. Now check out the following example. This CSS demonstrates how you can use the shorthand properties for padding:
    <!DOCTYPE HTML>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>CSS Margin and Padding Shorthand</title>
    <style type="text/css" media="screen">
    div {
    	border: 1px solid black;
    	margin: .75em;
    }
    
    div.one {
    	padding: 1em; /* sets the top, right, bottom and left padding to 1em. */
    }
    
    div.two {
    	padding: 1em 2em; /* sets the top and bottom to 1em and the right and left padding to 2em. */
    }
    
    div.three {
    	padding: 1em 2em 3em; /* sets the top to 1em, right and left to 2em, and bottom to 3em. */
    }
    
    div.four {
    	padding: 1em 2em 3em 4em; /* sets the top to 1em, right to 2em, bottom to 3em, and left to 4em. */
    }
    </style>
    </head>
    
    <body>
    	<div class="one">One value set: A <code>padding</code> value of 1em for all four sides.</div>
    	
    	<div class="two">Two values set: A <code>padding</code> value of 1em for the top and bottom, 2em for right and left.</div>
    	
    	<div class="three">Three values set: A <code>padding</code> value of 1em for the top, 2em for right and left, 3em for bottom.</div>
    	
    	<div class="four">Four values set: A <code>padding</code> value of 1em for the top, 2em for the right, 3em for the bottom, 4em for the left.</div>
    </body>
    </html>
    This code renders the following:
