This jsfiddle does what you want.

The way it works is with a main #wrap element that centres the content and creates a coordinate map for the absolutely positioned #main element. It does this because of its position: relative CSS rule. You end up with the following markup:

The header is then placed inside of this and given position: relative and a z-index to set it stacking above the #main container.

Finally #main is absolutely positioned below the header. The CSS looks like so:

/* centre content and create coordinate map for absolutely positioned #main */
#wrap {
    width: 300px;
    margin: 20px auto;
    position: relative;
}

header, #main {
    background: #fff;

    /* rounded corners */
    border: 1px solid #211C18;
    border-radius: 5px;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;    

    /* dropshadows */
    box-shadow: 2px 4px 20px #005377;
    -moz-box-shadow: 2px 4px 20px #005377;
    -webkit-box-shadow: 2px 4px 20px #005377;
}

header {
    display: block;
    width: 300px;
    height: 50px;

    /* stack above the #main container */
    position: relative;
    z-index: 2;
}

#main {
    width: 200px;
    height: 70px;

    /* stack below the header and underlap it...if that's even a word */
    position: absolute;
    z-index: 1;
    top: 40px;
    left: 50px;
}
