我正在尝试向我的网站添加粘性导航

Question

这是代码片段。我正在尝试向我的网站添加粘性导航：https://amrutabuge.com/

添加代码会显示导航，但它不具有粘性，并且汉堡包导航覆盖层不会显示背景。

这是代码

HTML

<!-- navigation bar -->
    <div class="navhamburger">
        <!-- title or logo to be deleted later-->
        <a href="#" class="logo">Title</a>
       
        <!-- hamburger icon -->
        <input class="side-menu" type="checkbox" id="side-menu"/>
        <label class="hamburger" for="side-menu">
            <span class="hamburger-line"></span>
        </label>
        
        <!-- menu -->
        <nav class="nav">
            <ul class="menu">
                <li><a href="#">Google Store</a></li>
                <li><a href="#">Google Search</a> </li>
                <li><a href="#">Spotify</a></li>
                <li><a href="#">Spotify Blog</a></li>
                <li><a href="#">Squarespace</a></li>
                <li><a href="#">Other work</a></li>
            </ul>
        </nav>
    </div>
