javascript - 在打开侧抽屉窗口跳到 html css 中的高度零

Question

我使用 HTML CSS、bootstrap 和一点点 javascript 制作了一个侧边抽屉。我也修复了导航栏。但问题是当触发侧抽屉时，我的窗口跳到零高度。我试图找到解决方案，但没有成功。

这些是我的代码。

$(".icon-box").click(function() {
    $("#sideToggleBtn").toggleClass("fa-bars fa-times");
    $(".sidenav").toggleClass("sidenav-open");
    $(".sidenav").css(
      "width",
      $(".sidenav").hasClass("sidenav-open") ? "450px" : "0px"
    );
  });

.sidenav {
    height: 100%;
    width: 0;
    position: fixed;
    z-index: 1000;
    top: 0;
    right: 0;
    background-color: $nav-Color;
    overflow-x: hidden;
    transition: 0.5s;
    padding-top: 60px;
  .closebtn {
    position: absolute;
    top: 0;
    right: 25px;
    font-size: 36px;
    margin-left: 50px;
  }
}
.sideNav-open{
    width: 450px;

}
.sideNav-close{
    width: 0px;
}

$(".icon-box").click(function() {
    $("#sideToggleBtn").toggleClass("fa-bars fa-times");
    $(".sidenav").toggleClass("sidenav-open");
    $(".sidenav").css(
      "width",
      $(".sidenav").hasClass("sidenav-open") ? "450px" : "0px"
    );
  });

.sidenav {
    height: 100%;
    width: 0;
    position: fixed;
    z-index: 1000;
    top: 0;
    right: 0;
    background-color: $nav-Color;
    overflow-x: hidden;
