使用 CSS 将导航栏固定在网页顶部
若要将导航栏固定在顶部,请使用position: fixed属性,以及top 属性。
你可以尝试运行以下代码,实现一个固定在顶部的菜单。
示例
<!DOCTYPE html> <html> <head> <style> ul { list-style-type: none; position: fixed; top: 0; width: 100%; } li { float: left; border-right: 1px solid white; } li a { display: block; padding: 8px; background-color: orange; } li:last-child { border-right: none; } div { padding:30px; margin-top:40px; background-color:white; } </style> </head> <body> <ul> <li><a href = "#home">Home</a></li> <li><a href = "#news">News</a></li> <li><a href = "#contact">Contact</a></li> <li><a href = "#about">About</a></li> </ul> <div> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> <p>Adding demo text to check fixed menu.</p> </div> </body> </html>
