z-index - logo is going behind header

I am making a website however my logo is going behind the header even though the z-index is set higher. I do not know why? I have set a positioning so why is it not working? The overlays are both transparent .png s as I wanted to make it compatible with all browsers and RGBa is not.

Photo of the problem

The css is:

@charset "utf-8";

body {
    margin-left: 0px;
    margin-right:0px;
    margin-top: 0px;
    padding:0px;
    z-index:-101;
}

#wrapper{
    margin-left:17.3875%;
}

#BG {
    height: auto;
    width: 100%;
    position: fixed;
    z-index: -100;
    left: 0px;
    top: 0px;
    min-height: 100%;
    min-width: 1040px;
}
/*HEADER*/
/*===================================================================*/
#header{
    margin:0px;
    padding:0px;
    z-index:-98;
    position:fixed;
    z-index:-99;
    width:65.225%;
    height:18.2022472%;
    background:url(WireFrame/Nav%20Bar.png)
}

.logocontainer{
    width:34.1510157%;
    height:100%;
    margin:0;
    padding:0;
    z-index:-1;
    position:absolute;
    }

.logoimage{
    max-height:100%;
    max-width:100%;
    z-index:1;
    position:absolute;
}

#navigation{

}
/*BODY*/
/*===================================================================*/
#bodyoverlay{
    background:url(WireFrame/Body.png);
    position:fixed;
    z-index:-99;
    height:100%;
    width:65.225%;
    background-repeat:repeat-y
}

#body{
    z-index:-98;
    height:100%;
    width: 100%;

}

The html is:

<!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">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Home</title>
<link href="CSS.css" rel="stylesheet" type="text/css" />
</head>

<body>
<img src="file:///U|/Year 8/ICT/Webdesign/WireFrame/Background.jpg" name="BG" width="4000" height="2670" id="BG" />
<div id = "wrapper">
    <header>
    <div id = "header">
        <div class="logocontainer">
        <img src="WireFrame/Logo.png" class="logoimage" />        </div>
        <nav>
            <div id = "navigation">         </div>
        </nav>
    </div>
    </header>
    <!---->
    <div id = "body">
        <div id = "bodyoverlay">
        </div>
        <div id = "Content">
        </div>
    </div>
</div>
</body>
</html>

There are a number of things wrong with the way you are using the z-index property:

  • Firstly, you have to define a position for each element that has a z-index.
  • Secondly, z-index does not order everything in a page absolutely -- there are different stacking contexts.
  • (You also have multiple z-indexes in the #header)

Here's an excellent article on z-index that everyone should read and that should hopefully help you clear up the issues in your code.

Items that are part of the layout should be CSS backgrounds, not inline images. It makes all of these issues suddenly go away.
