它看起来更像比分部表给我...

It looks much more like a table than divisions to me...

<table class="header"><tr>
    <td class="left"></td>
    <td class="center">
        <img class="logo" src="linktomyimage.com/image.png" />
    </td>
    <td class="right"></td>
</tr></table>

想想这样的CSS算账：

Think about so CSS afterwards :

table.header{
    width: 100%;
    border-collapse: collapse;
}

table.header td{
    vertical-align: top;
    border: 1px solid #404040;
}

table.header td.center{
    width: 800px;
    height: 600px;
}

这仅仅是一个code样品，有想法，并适应自己的需要^^

This is just a code sample, get the idea, and adapt to your own needs ^^
