これは、背景画像とタグ内のナビゲーションを持つ.headerクラスです。私がやろうとしているのは、背景画像を.headerから分離し、それを新しいdivに配置することです (ナビゲーションの後ろに移動しますが、同じ位置を維持します)。これにより、いくつかのフィルターを追加してさらにカスタマイズできます。

<style>
.header {
    float: left;
    height: 300px; 
    width: 100%;
    margin-top: 2%;
    -webkit-border-top-left-radius: 6px;  
    -webkit-border-top-right-radius: 6px;
    -moz-border-radius-topleft: 6px;
    -moz-border-radius-topright: 6px;
    background-image: url(../5898169717_6f4b2a3515_b.jpg);
    background-position: center center;
    background-repeat: no-repeat;
    background-size: auto;
    background-color: #91918e;
}

.header .nav-header { margin-top: 15px; padding-left: 30px; padding-right: 50px; }

これはどうですか: http://jsfiddle.net/Xm5BE/

HTMLは次のとおりです。

<header>    
    <div class="nav">
        <ul>
            <li><a href="#">Link 1</a></li>
            <li><a href="#">Link 1</a></li>
            <li><a href="#">Link 1</a></li>
            <li><a href="#">Link 1</a></li>
        </ul>        
    </div>
    <div class="header">This is the header bg div</div>    
</header>

そしてCSS：

header { background:black ;
    width:100% ;
    height:200px ;
    position:relative ;
}

.header { position:absolute ;
    left:0 ;
    top:0 ;
    width:100% ;
    height:200px ;
    background:blue ;
    z-index:100 ;
}

.nav { width:100% ;
    height:28px ;
    background:yellow ;
    position:relative ;
    top:120px ;
    z-index:500 ;
}

.nav ul { margin-left:0 ;
    padding-left:0 ;
    list-style-type:none ;
    text-align:center ;
}

.nav li { display:inline ;
}

.nav li a { padding:0px 8px ;
    line-height:28px ;
    font-size:14px ;
    font-family:arial ;
}
