希望我能在这里找到帮助。我试图让这个导航栏响应。我从 w3schools tut 开始，但我丢失了我的 css 文件的概述，并且无法找到为什么这不起作用的问题。感谢您的帮助!

最佳答案

你有几个问题。首先，您在未应用于 anchor (a 元素)的媒体查询中使用类选择器 .icon 像下面这样的东西会修复它:

<li><a class="icon" href="http://www.air-transfer.at/">Home</a></li>

此外，在您的 JS "menu li" 中是一个标签选择器，并且没有菜单标签。您需要一个类选择器 ".menu li" ，而 getElementById 将无法与您想要的“css 选择器”一起使用 querySelectorAll 见下文:

window.onload = myFunction

function myFunction() {
    var x = document.querySelectorAll(".menu li");
    for(var i=0; i< x.length; i++) {
      if (x[i].className === "") {
          x[i].className += " responsive";
      } else {
          x[i].className = "";
      }      
    }
}
