How to Adjust Margins with CSS

The margin property is used to specify the margin around an element. It can be applied to both block and inline elements. Margins can be specified in number of units (e.g., 20px) or in percentage of the width of the containing element. Learn how to adjust margins with CSS below.

Each side of an element can have a different margin. The properties for this are:

  • margin-top
  • margin-right
  • margin-bottom
  • margin-left

Start with a standard HTML document, then add the div tags with the style information in them, like so:

<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>CSS Margin</title>
</head>
<body>
<h1>CSS Margin</h1>
<div style="background-color: #0066ff; 
			border: 5px solid #ff99ff; padding: 0px;">
	<div style="background-color: #ff6600; border: 2px solid black; 
			margin-top: 30px; margin-right: 30px; 
			margin-bottom: 30px; margin-left: 30px;">
				margin-top: 30px;<br>
				margin-right: 30px;<br>
				margin-bottom: 30px;<br>
				margin-left: 30px;
	</div>
</div>
<hr>
<div style="background-color: #0066ff; 
			border: 5px solid #ff99ff; padding: 0px;">
	<div style="background-color: #ff6600; 
			border: 2px solid black; margin: 30px;">
				margin: 30px;
	</div>
</div>

</body>
</html>

This code will render the following:
