Question

我正在按照教程制作网站导航栏。在处理移动菜单的响应性时，我制作了一个.burger类，其中包含三个栏来代表较小屏幕的菜单图标。我做了这样的设置，以便在超过775px的屏幕上将其display属性设置为none。并使用媒体查询进行设置，以便在较小的屏幕上加载我的网站时显示菜单图标。使用一些JavaScript，我添加了一个事件侦听器，以便单击以显示所有链接并播放流畅的动画。由于某些原因，当用户单击图标时，站点不会更改。

const navSlide = () => {
  const burger = document.querySelector('.burger');
  const nav = document.querySelector('#nav');

  burger.addEventListener('click', () => {
    console.log(nav.classList.toggle('nav-active'));
  });
};

navSlide();

对CSS进行以下更改：

更改此

.nav-active {
  transform: translateX(0%);
}

 }

const navSlide = () => {
  const burger = document.querySelector('.burger');
  const nav = document.querySelector('#nav');

  burger.addEventListener('click', () => {
