Question

目前正在做一个快速的网站。得到了导航样式并且工作正常，但是我将下拉列表作为导航项目实现了。这导致了我似乎无法解决的三个问题：

在导航切换中，内容相互重叠。
在导航切换中，导航会让您滚动，即使在那里也是如此是悬浮在桌面屏幕上的下拉菜单的空间。
在桌面屏幕上，导航项会导致使用滚动条在标题内发生删除。

一直坚持这一点，我们将不胜感激。

function NavToggle() {
  var tn = document.getElementById("nav-bar")
  if (tn.style.display === "none") {
    tn.style.display = "block";
  } else {
    tn.style.display = "none";
  }
}
