将＃max-width:1250px;设置在您的#container当前位于您的身体上。这样，你的头将是他父母的100％（体）:)

可以使用的容器元素达到的效果，那么就设置包含元素保证金0 auto，这将是居中。

标记

<div id="header"> 
    <div id="headerContent"> 
     Header text 
    </div> 
</div>

CSS

#header{ 
    width:100%; 
    background: url(yourimage); 
} 
#headerContent{ 
    margin: 0 auto; width: 960px; 
}

JSFiddle演示的工作原理包括normalized.css（https://github.com/necolas/normalize.css/）。除非我也将H1的边距设置为0px，否则这个代码在Chrome上不适用于我。 – WoodenKitty

@WoodenKitty很好的接收！嘿，这个答案老老实实地说，现在老实说..使用ID的*不寒而栗*。我继续前进并删除H1，因为无论如何它都不需要，并且会减少混淆。 – Loktar

从body取出max-width，并把它放到#container。

因此，而不是：

body { 
    max-width:1250px; 
}

你应该有：

#container { 
    max-width:1250px; 
}

#header { 
margin: 0; 
padding: 0; 
width: 100%; 
background: xxxx; 
} 

#header #content { 
margin: 0px auto; 
width: 800px; /* or whatever */ 
} 

<div id="header"> 
<div id="content"> 
stuff here 
</div> 
</div>
