Question

我是整个HTML和CSS的新手，但到目前为止一直没事。

现在我需要将标题粘贴到顶部，因此当向下滚动时它会保持在顶部，而其他内容会滚动到顶部。

我一直在谷歌搜索和搜索，找不到最好的解决方案，我希望你能帮助我！

仅供参考我正在使用960网格。

以下是代码：

    <div class="container_12">
    <header class="fixed">
        <img src="img/logolangt.jpg" alt="MB it logo" class="grid_12"/>
        <nav class="grid_12" id="mainnav">
            <ul>
                <li><a href="index.html" class="selected">Services</a></li>
                <li><a href="career.html">Career</a></li>
                <li><a href="clients.html">Clients</a></li>
                <li><a href="about us.html">About</a></li>
            </ul>
        </nav>
        <nav class="grid_12" id="servicesnav">
            <ul>
                <li><a href="#">HCM</a></li>
                <li><a href="#">SAP</a></li>
                <li><a href="#">SuccessFactors</a></li>
                <li><a href="#">Support</a></li>
            </ul>
        </nav>
    </header>

这是CSS代码：

    .container_12 {
background: white;  
}

/*

header img {

你只需要把它放在你的CSS中。

#mainnav {
    position:fixed;
}

看一下http://jsfiddle.net/qxXXw/你也可能想看看http://www.w3schools.com/css/css_positioning.asp以便更好地了解css位置，我知道我花了一些时间来弄清楚它。< / p>
