Remarks
You should use the left attribute only when the position attribute is set; otherwise, the value of the left attribute is ignored.
Because the value of the left property is a string, you cannot use the property in script to calculate the position of the object in the document; instead, you should use the pixelLeft property or the posLeft property.

Examples
The following examples use the left attribute and the left property to change the position of the object.
This example uses an inline style sheet to set the position of an image 100 pixels to the right of the parent object's left edge.

<DIV STYLE="position:absolute;left:100px"> <IMG SRC="cone.jpg"></DIV>
This example uses inline scripting to change the position of two images when an onclick event occurs.
Code example: http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/refs/left_s.htm
<BUTTON onclick="cone.style.left='100px'; sphere.style.left='200px'"> . . .</BUTTON>
