Style Object Reference Style Object

Definition and Usage

The margin property sets or returns the margins of an element.

This property can take from one to four values:

  • One value, like: div {margin: 50px} - all four margins will be 50px
  • Two values, like: div {margin: 50px 10px} - the top and bottom margins will be 50px, left and right margins will be 10px
  • Three values, like: div {margin: 50px 10px 20px}- the top margin will be 50px, left and right margin will be 10px, bottom margin will be 20px
  • Four values, like: div {margin: 50px 10px 20px 30px} - the top margin will be 50px, right margin will be 10px, bottom margin will be 20px, left margin will be 30px

Syntax

Set the margin property:

Object.style.margin="%|length|auto|inherit"

Return the margin property:

Object.style.margin

Value Description
% Defines the margins in % of the width of the parent element
length Defines the margins in length units
auto The browser sets the margins (all four margins will be equal)
inherit The margins are inherited from the parent element

Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The margin property is supported in all major browsers.

Note: The value "inherit" is not supported in IE7 and earlier. IE8 requires a !DOCTYPE. IE9 supports "inherit".

Tips and Notes

Both the margin property and the padding property insert space around an element. However, the difference is that margin inserts the space around the border, while padding inserts the space within  the border of an element.

Example

Example

Change the margins of a div element:

<html>
<head>
<style type="text/css">
#ex1
{
border: 1px solid #FF0000;
}
</style>
<script type="text/javascript">
function displayResult()
{
document.getElementById("ex1").style.margin="100px";
}
</script>
</head>
<body>

<div id="ex1">This is some text.</div>
<br />
<button type="button" onclick="displayResult()">Change margin</button>

</body>
</html>
