<style>
body {
margin: 0;
}
header {

<li><a href="#">菜单4</a></li>
</ul>
</nav>
</header>
<main>
<!-- 页面内容 -->
</main>
</body>
</html>In the above code, use position: sticky; to set sticky positioning, top: 0; means navigation The menu is fixed at the top of the page. nav ul and nav li are used to set the menu style.
