Question

我现在正在使用html和css（没有js）制作汉堡菜单，并且：checked + .something无法正常工作。我正在寻找约3个小时的解决方案，但找不到任何解决方案。如果您能帮助我，那将是很好。也许我在某个地方弄乱了，因为我从视频中观看了它，但是我做了和他完全一样的事情，但是我没有用:( 这是代码：

* {
  margin: 0;
  padding: 0;
}

body {
  background-color: teal;
}

.navigations {
  right: 0;
  z-index: 10;
  display: block;
  position: fixed;
  top: 15px;
  padding-bottom: 20px;
  padding-left: 25px;
  padding-right: 150px;
  border-radius: 50px 10px 10px 50px;
  background: rgba(0, 0, 0, 0.5);
}

.navigations div {
  display: inline-block;
  font-size: 25px;
}

.navigations a {
  text-decoration: none;
  color: white;
}

.burger {
  z-index: 100;
  position: fixed;
  right: 25px;
  display: block;
  top: 25px;
  cursor: pointer;
}

.burger div {
  width: 45px;
  height: 5px;
  background-color: white;
  margin: 12px;
  border-radius: 10px;
}

#toggle {
  display: none;
  position: fixed;
}

#toggle:checked+.navigations {
  display: none;
}

<html>

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale = 1.0">
  <link rel="stylesheet" type="text/css" href="something.css">
</head>

<body>
  <div class="navigations">
    <div class="nav">
      <a href="">About us</a>
    </div>
    <div class="nav">
      <a href="">Tours</a>
    </div>
    <div class="nav">
      <a href="">Contacts</a>
    </div>
  </div>
  <label for="toggle">
      <div class="burger">
          <div class="burgerelem"></div>
          <div class="burgerelem"></div>
          <div class="burgerelem"></div>
      </div>
  </label>
</body>

似乎您实际上缺少了checkbox元素。由于您使用的是adjacent sibling selector（+中的#toggle:checked + .navigations），因此应将.navigations div的复选框立即放在

#toggle

* { margin: 0; padding: 0; } body { background-color: teal; } .navigations { right: 0; z-index: 10; display: block; position: fixed; top: 15px; padding-bottom: 20px; padding-left: 25px; padding-right: 150px; border-radius: 50px 10px 10px 50px; background: rgba(0, 0, 0, 0.5); } .navigations div { display: inline-block; font-size: 25px; } .navigations a { text-decoration: none; color: white; } .burger { z-index: 100; position: fixed; right: 25px; display: block; top: 25px; cursor: pointer; } .burger div { width: 45px; height: 5px; background-color: white; margin: 12px; border-radius: 10px; } #toggle { display: none; position: fixed; } /* Since the .navigations is the next sibling element after #toggle, the + selector works here */ #toggle:checked+.navigations { display: none; }

纯HTML和CSS汉堡菜单不起作用
