CSS Position

Hi, i am simply trying to alert the left position of a css layer.

Javascript:

var Element = document.getElementById('box');
alert(Element.style.left);


CSS

#box {position:absolute;
left:150px;
top:150px;
background-color:blue;
height:100;
width:100;}


HTML

<div id="box">
</div>


The problem is the alert is blank and i can't understand why.

thanks
