Question

我使用纯HTML，CSS和JS创建的汉堡菜单在单击时不会打开，我不知所措。目标是使汉堡菜单显示在移动视图中，并在切换时使用100％的屏幕宽度显示导航。这也是我的代码的代码库。 https://codepen.io/alec-johnson/pen/dyMgKeN

const toggleButton = document.querySelector('.toggle-button');
const navbarLinks = document.querySelector('.navbar-links');

toggleButton.addEventListener('click', () => {
  navbarLinks.classList.toggle('active');
});

@import url('https://fonts.googleapis.com/css2?family=Lato&display=swap');
body {
  margin: 0;
  padding: 0;
}

.navbar {
  display: flex;
  position: relative;
  justify-content: space-between;
  align-items: center;
  background-color: rgba(121, 173, 173, 0.3);
  color: rgb(87, 82, 82);
}

.brand-title {
  font-family: 'Lato', sans-serif;
  font-size: 1.5rem;
  margin: .5rem;
}

.navbar-links {

}

.navbar-links ul {

.navbar-links li:hover {
  background-color: #555;
}

.navbar-links li a:hover {

Answer 1

在此处删除.navabr-links

.navabr-links.active {display: flex;} 所以会的 .active {display: flex;}

const toggleButton = document.querySelector('.toggle-button');
const navbarLinks = document.querySelector('.navbar-links');

toggleButton.addEventListener('click', () => {
  navbarLinks.classList.toggle('active');
});

@import url('https://fonts.googleapis.com/css2?family=Lato&display=swap');
body {
  margin: 0;
  padding: 0;
}

.navbar {
  display: flex;
  position: relative;
  justify-content: space-between;
  align-items: center;
  background-color: rgba(121, 173, 173, 0.3);
  color: rgb(87, 82, 82);
}

.brand-title {
  font-family: 'Lato', sans-serif;
  font-size: 1.5rem;
  margin: .5rem;
}

.navbar-links {
  height: 100%;
}

.navbar-links ul {
  margin: 0;
  padding: 0;
  display: flex;
}

.navbar-links li {
  list-style: none;
}

.navbar-links li a {
  font-family: 'Lato', sans-serif;
  text-decoration: none;
  color: rgb(87, 82, 82);
  padding: 1rem;
  display: block;
}

.navbar-links li:hover {
  background-color: #555;
}

.navbar-links li a:hover {
  color: rgba(121, 173, 173);
}

.toggle-button {
  position: absolute;
  top: .75rem;
  right: 1rem;
  display: none;
  flex-direction: column;
  justify-content: space-between;
  width: 30px;
  height: 21px;
}

.toggle-button .bar {
  height: 3px;
  width: 100%;
  background-color: rgb(87, 82, 82);
  border-radius: 10px;
}

@media (max-width: 800px) {
  .toggle-button {
    display: flex;
  }
  .navbar-links {
    display: none;
    width: 100%;

  .navbar {
