如何移动 ul div 显示块

Question

如何将移动视图中的菜单图标切换到屏幕左侧（名称正下方和名称行）后出现的导航链接（工作和联系人）。目前在媒体查询中定位#js-menu.main-nav.active，但没有成功。

在桌面视图中，一切都是应该的，但是当我缩小到移动设备并单击图标时，导航链接不在正确的位置。

let mainNav = document.getElementById("js-menu");
let navBarToggle = document.getElementById("js-navbar-toggle");

navBarToggle.addEventListener("click", function() {
  mainNav.classList.toggle("active");
});

.navbar {
  display: flex;
  justify-content: space-between;
  padding-bottom: 0;
  height: 70px;
  align-items: center;
}

.main-nav {
  display: flex;
  margin-right: 30px;
  flex-direction: row;
  justify-content: flex-end;
}

.main-nav li {
  margin: 0;
  list-style-type: none;
}

.nav-links {
  margin-left: 40px;
}

.logo {
  margin-top: 0px;
  margin-left: 20px;
}

.navbar-toggle {
  display: none;
}

.nav-links,
.logo {
  text-decoration: none;
  color: black;
}

.navbar {
  font-size: 18px;
  padding-bottom: 10px;
  background: pink;
}

@media screen and (max-width: 500px) {
  .navbar-toggle {
    position: absolute;
    top: 30px;
    right: 30px;
    display: block;
    cursor: pointer;
    font-size: 18px;
  }
  #js-menu.main-nav.active {
    display: block;
    text-align: left;
    margin: 15px 15px 15px 0px;
    padding-bottom: 4px;
  }
  .logo {
    display: inline-block;
    font-size: 18px;
    margin-left: 20px;
  }
  .main-nav li {
    text-align: left;
    margin: 15px 15px 15px 0px;
    padding-bottom: 4px;
  }
  .main-nav {
    list-style-type: none;
    display: none;
    padding: 0px 20px;
  }
}

如果我没理解错的话，你想做这样的事情。这应该给你正确的方向。基本上你硬编码了 height: 70px; of .navbar。这就是为什么它没有在切换时展开。

let navBar = document.querySelector(".navbar");
let mainNav = document.getElementById("js-menu");
let navBarToggle = document.getElementById("js-navbar-toggle");

navBarToggle.addEventListener("click", function() {
  mainNav.classList.toggle("active");
  navBar.classList.toggle("active");
});

.navbar {
    display: flex;
    justify-content: space-between;
    padding-bottom: 0;
    height: 70px;
    align-items: center;
  }

.main-nav {
    display: flex;
    margin-right: 30px;
    flex-direction: row;
    justify-content: flex-end;
  }

  .main-nav li {
    margin: 0;
    list-style-type: none;
  }

  .nav-links {
    margin-left: 40px;
  }

  .logo {
    margin-top: 0px;
    margin-left: 20px;
  }

  .navbar-toggle {
    display: none;
  }

.nav-links,
.logo {
  text-decoration: none;
  color: black;
}

.navbar {
  font-size: 18px;
  padding-bottom: 10px;
  background: pink;
}
.navbar.active{
  height: unset;
  flex-direction: column;
  align-items: flex-start;
  padding-top: 24px;
}

@media screen and (max-width: 500px){

 .navbar-toggle {
  position: absolute;
  top: 30px;
  right: 30px;
  display: block;
  cursor: pointer;
  font-size: 18px;
}

#js-menu.main-nav.active {
  display: block;
  text-align: left;
  margin: 0;
  margin-top: 4px;
  padding: 0px;
}

#js-menu.main-nav.active .nav-links {
  margin-left: 20px;
} 

.logo {
  display: inline-block;
  font-size: 18px;
  margin-left: 20px;
}

.main-nav li {
  text-align: left;
  margin: 15px 15px 15px 0px;
  padding-bottom: 4px;
}


.main-nav {
  list-style-type: none;
  display: none;
  padding: 0px 20px;
}  

}
