溢出：隐藏，清除：使用float后，两者和清除修复都无法正常工作

标签： html css

我正在尝试使用html和css创建一个简单的信息网站，并使用960网格，因为该网站将具有圆柱结构。

当我将标题h1向左浮动（其中包含徽标的图像，我使用css添加图像作为背景）和右侧的导航列表时，它下面的所有内容都会浮动并在使用溢出后：隐藏，它不清除浮动。 我已经尝试了960网格的明确修复类，也是明确的：两者。但他们也没有工作。

所以请告诉我我做错了什么。

这是css 

    /**** =header ****/
header {
    overflow: hidden;
}

header h1 {
    background: url(../img/logo.png) no-repeat;
    text-indent: -9999px;
    height: 23px;
    width: 174px;
    float: left;
}

/**** =nav ****/

nav {
    float: right;
}

nav li {
    display: inline;
}

/**** =banner ****/

.banner {
    background: url(../img/city-bg.jpg) no-repeat;
    width:695px;
    height:231px; 
}

.callout {
    background: black;
    height: 231px;
}

这是html

<head>
    <meta charset="utf-8" />
    <titel></title>
    <link rel="stylesheet" href="css/reset.css">
    <link rel="stylesheet" href="css/text.css">

我通常做的是创建一个.clear类：

.clear {
    clear:both;
}

把它放在浮动的元素之后。在这种情况下nav我认为是这样的：

<h1>Title</h1>
<nav>
    <!-- nav elements -->
</nav>
<div class="clear"></div>

但如果你有.clearfix类，请使用它。
