I have a div, i want get height of the div.

```
$('.graph_container').css('height')

```

and css is 

```
.graph_container {
    width:100%;
    float:left;
    border:1px solid #CCCCCC;
    margin-top:1em;
    position:relative;
}

```

since height is not mentioned, in IE it give 'auto'. How can i get exacte height.

I appreciate your suggestions.
