Question

我创建了一个导航栏，所有选项卡都是内联的。减小窗口大小时，会出现条形图标，并且选项卡将垂直显示，而不是水平显示。我需要输出，以便在减小窗口大小时出现条形图标，但选项卡消失，并且仅在单击条形图标时才能（垂直）看到和看不见。我尝试了jquery，但是没有用。我不确定该怎么做，您能帮我吗？

body {
  margin: 0;
  padding: 0;
  font-family: Sans-Serif;
}

nav {
  margin-left: 45px;
  ;
  width: 90%;
  background: #D1D0D3;
}

ul {
  list-style-type: none;
  width: 80%;
  margin: 0 auto;
  color: black;
  padding: 0;
}

ul a {
  color: black;
  text-decoration: none;
}

ul li {
  display: inline-block;
  padding: 20px;
}

ul li:hover {
  background-color: yellow;
}

.toggle {
  width: 100%;
  padding: 10px 20px 0px 20px;
  background-color: #C2ABF1;
  text-align: right;
  box-sizing: border-box;
  color: white;
  font-size: 30px;
  display: none;
}

@media (max-width: 800px) {
  .toggle {
    display: block;
  }
  .block {
    display: block;
  }
}

<div class="toggle">
  <i class="fa fa-bars menu" id="menu"></i>
</div>
<nav>
  <ul class="ul">
    <li class="block"><a href="#">Home</a></li>
    <li class="block"><a href="#">About</a></li>
    <li class="block"><a href="#">Makeup</a></li>
    <li class="block"><a href="#">Hairstyle</a></li>

Answer 1

添加此jquery代码

$(".menu").on("click", function() {
  $("nav .ul").toggle(500);
})

媒体查询中的此CSS

.ul {
    display: none;
  }
  nav {
      margin-left: 0;
      width: 100%;
  }

$(".menu").on("click", function() {
  $("nav .ul").toggle(500);
})

body {
  margin: 0;
  padding: 0;
  font-family: Sans-Serif;
}

nav {
  margin-left: 45px;
  ;
  width: 90%;
  background: #D1D0D3;
}

ul {
  list-style-type: none;
  width: 80%;
  margin: 0 auto;
  color: black;
  padding: 0;
}

ul a {
  color: black;
  text-decoration: none;
}

ul li {
  display: inline-block;
  padding: 20px;
}

ul li:hover {
  background-color: yellow;
}

.toggle {
  width: 100%;
  padding: 10px 20px 0px 20px;
  background-color: #C2ABF1;
  text-align: right;
  box-sizing: border-box;
  color: white;
  font-size: 30px;
  display: none;
}

@media (max-width: 800px) {
  .toggle {
    display: block;
  }
  .block {
    display: block;
  }
  .ul {
    display: none;
  }
  nav {
    margin-left: 0;
    width: 100%;
  }
}
