How to use HTML and CSS to implement a layout with a fixed navigation menu

In modern web design, the fixed navigation menu is one of the common layouts. It can keep the navigation menu always at the top or side of the page, allowing users to browse web content conveniently. This article explains how to implement a layout with a fixed navigation menu using HTML and CSS, and provides specific code examples.

First, you need to create an HTML structure to present the content of the web page and the navigation menu. The following is a simple sample code:

<!DOCTYPE html>
<html>
<head>
    <title>固定导航菜单示例</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <header class="navbar">
        <nav>
            <ul>
                <li><a href="#">首页</a></li>
                <li><a href="#">关于我们</a></li>
                <li><a href="#">产品</a></li>
                <li><a href="#">联系我们</a></li>
            </ul>
        </nav>
    </header>
    
    <main>
        <!-- 网页内容 -->
    </main>
    
    <footer>
        <!-- 网页底部内容 -->
    </footer>
</body>
</html>

In the above code, the <header></header> element contains a navigation menu, and the <ul></ul> element represents Menu items, <li> elements represent each specific menu item, and <a></a> elements represent links.

Next, we need to use CSS to achieve the effect of a fixed navigation menu. The following is a simple CSS code example:

body {
    margin: 0;
    padding: 0;
}

.navbar {
    position: fixed;
    top: 0;
    width: 100%;
    background-color: #333;
    padding: 10px;
}

.navbar ul {
    list-style: none;
    margin: 0;
    padding: 0;
}

.navbar ul li {
    display: inline-block;
    margin-right: 10px;
}

.navbar ul li a {
    color: #fff;
    text-decoration: none;
}

.main {
    margin-top: 60px; /* 为了避免导航菜单遮挡网页内容，将内容下移 */
    padding: 20px;
}

footer {
    height: 100px;
    background-color: #f2f2f2;
}

The .navbar class in the above CSS sets the fixed position and style of the navigation menu, and the .main class sets the content Moved down to avoid being obscured by the menu, footer styles the bottom of the page.

Use the above HTML and CSS code, open the web page in the browser, and you will see a layout with a fixed navigation menu. You can modify the menu style and fill the web page content according to actual needs.
