HTML DOM marginWidth Property

Frame Object Reference Complete Frame Object Reference

Definition and Usage

The marginWidth property sets or returns the left and right margins of a frame (in pixels).

Syntax

frameObject.marginWidth=pixels

Example

In our example we will first create an HTML document containing a frameset with two columns. Each column is set to 50% of the browser window:

<html>
  <frameset cols="50%,50%">
    <frame id="leftFrame" marginwidth="50"
    src="frame_marginwidth.htm">
    <frame id="rightFrame" marginwidth="20"
    src="frame_a.htm">
  </frameset>
</html>

The HTML document "frame_marginwidth.htm" is put into the first column, and the HTML document "frame_a.htm" is put into the second column.

The source of "frame_marginwidth.htm" is as follows:

<html>
<body>
script type="text/javascript">
x=parent.document.getElementById("leftFrame");
y=parent.document.getElementById("rightFrame");
document.write("Left/Right margins for leftFrame: ");
document.write(x.marginWidth);
document.write("<br />Left/Right margins for rightFrame: ");
document.write(y.marginWidth);
</script>
</body>
</html>
