javascript - 打开和关闭侧导航菜单以及导航栏问题

Question

我在这里遇到了几个问题。我正在尝试有一个锁定的顶部栏，这确实有效。然而，即使我放置了一些项目，例如橙色动画按钮，它也会出现在文本链接之前的栏上。第二。我希望可以使用动画按钮来关闭页面右侧的弹出菜单。抱歉，如果这真的很简单，我在这里错过了。我仍在学习这些东西。

    function myFunction(x) {
    x.classList.toggle("change");
    }
 
    function openNav() {
    document.getElementById("mySidenav").style.width = "250px";
    }

    function closeNav() {
    document.getElementById("mySidenav").style.width = "0";
    }

    body {
    font-family: "Lato", sans-serif;
    }

    .sidenav {
     height: 100%;
     width: 0;
     position: fixed;
     z-index: 1;
     top: 0;
     right: 0;
     background-color: #111;
     overflow-x: hidden;
     transition: 0.5s;
     padding-top: 60px;
     }

     .sidenav a {
     padding: 8px 8px 8px 32px;
     text-decoration: none;
     font-size: 25px;
     color: #818181;
     display: block;
     transition: 0.3s;
     }

     .sidenav a:hover, .offcanvas a:focus{
     color: #f1f1f1;
     }

     .sidenav .closebtn {
     position: absolute;
     top: 0;
     right: 25px;
     font-size: 36px;
     margin-left: 50px;
     }

    @media screen and (max-height: 450px) {
    .sidenav {padding-top: 15px;}
    .sidenav a {font-size: 18px;}
     }

    }

    form {
    margin: 0px;
    padding: 0px;
    }

    .main {
    padding: 10px;
    margin-top: 30px;
    }



     /*animated button*/
     .container {

    .bar1, .bar2, .bar3 {

    transform: rotate(-45deg) translate(-9px, 6px) ;
    }

    .change .bar2 {opacity: 0;}

    .change .bar3 {
    -webkit-transform: rotate(45deg) translate(-8px, -8px) ;
    transform: rotate(45deg) translate(-8px, -8px) ;
    }

希望这有帮助:

<div class="navbar" style="z-index: 1000">
   <font size=20 color=white>&nbsp;
        <b>Website</b></font>

   <span style="font-size:30px;cursor:pointer;float:right;">
        <div class="container" onclick="myFunction(this)">
            <div class="bar1"></div>
            <div class="bar2"></div>
            <div class="bar3"></div>
        </div>
    </span>
    <a href="#link">Link</a>
    <a href="#Link2">Another Link</a>
    <a href="#contact">Contact</a>
    <a href="#about">About</a> &nbsp;&nbsp;&nbsp;&nbsp;
</div>

<script>
    function myFunction(x) {
        x.classList.toggle("change");
        var mySidenavWidth = document.getElementById("mySidenav").style.width;

        if (mySidenavWidth === "250px")
             closeNav();
        else
             openNav();               
    }
    function openNav() {
        document.getElementById("mySidenav").style.width = "250px";
    }

    function closeNav() {
        document.getElementById("mySidenav").style.width = "0px";
    }
</script>
