Html/Css - How to get an image to stretch 100% width of a container then display another image over it?

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8" />
    <title>Render this</title>
    <style type="text/css">
#header {
    position:relative;
    height: 130px;
    margin: 5px 5px 0 5px;
    border: #0f0f12 outset 2px;
    border-radius: 15px;
}

#loginBox {
    position:relative;
    float: right;
    width: 23.5%;
    height: 128px;
    font-size: 75%;

}

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

.logo {
    position:relative;
    width: 50%;
    height: 120px;
    float: left;
    display: block;
    padding: 5px;
}
    </style>
</head>
<body>
<div id="header">
    <img src="img/headerBg.jpg" alt="" class="headerBg" />
    <a href="/"><img src="img/logo.png" alt="Logo" class="logo" /></a>
    <div id="loginBox">
        other code
    </div>
</div>

</body>
</html>


.header {
    position: relative;
}

.headerBg {
    position: absolute;
    left: 0px;
    right: 0px;
    width: 100%;
}

Note that this will scale the image to fit the width of the <div>; if you only want it to resize horizontally then you should set the height explicitly.

You could also try max-width: 100%; if you only want the image to scale on large windows.
