ok, I’ve searched through the other cries for help and nothing was similar to my site or helped in anyway so yes, yet again here is another firefox 100% height problem

Here is my XHTML code

```php
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> 
<head runat="server">
    <title>HELP</title>
</head>
<body>

    <div class="centerspace">
        
        <div class="theleft">&nbsp;</div>
        <div class="themiddle">       
            MID
        </div>
        <div class="theright">&nbsp;</div>
        
    </div>

</body>
</html>

```

themiddle div is where the content will go, the left and the right divs are going down both sides and will have a background image with a drop shadow effect…

anyway the height:100% is working in IE, not Firefox…attached the CSS as a text file and I would appreciate any help…

Thanks :beam:
