Question

我想知道如何让我的网站有一个固定的顶部横幅，它的水平导航栏，所以当人们滚动浏览网站时，横幅和导航将保持其位置，而内容将正常滚动。 / p>

HTML：

<!doctype html>
<html lang="en">

    <head>
        <meta charset="utf-8" />
        <title>Play - Learn - Grow</title>
        <link rel="stylesheet" href="main.css">

    <body class="body">

        <span class="banner_h">
            <img src="Images\Top_Banner_4.png" alt="Banner" height="150" width ="1240" />
        </span>

        <nav>
            <ul class="nav">

您必须将横幅和导航包装在固定位置元素

中

HTML（仅限标题）

<header>
    <span class="banner_h">
        <img src="Images\Top_Banner_4.png" alt="Banner" height="150" width ="1240" />
    </span>

    <nav>
        <ul class="nav">
            <li><a href="index.html">Home</a></li>
            <li><a href="about.html">About Us</a></li>
            <li><a href="contact.html">Contact Us</a></li>
            <li><a href="membership.html">Become a Member</a></li>
            <li><a href="borrow.html">Borrow Toys</a></li>
            <li><a href="policies.html">Our Policies</a></li>
            <li><a href="sitemap.html">Site Map</a></li>
        </ul>
    </nav>
</header>

CSS：

 header {
     position:fixed;
     top: 0;
     left: 0;
     width: 100%;
 }
