Question

我这里有一个横向的CSS下拉菜单，从网上获取。我整整都搜索了如何将这个水平菜单转换为垂直下拉菜单。以及如何制作子菜单。如果可能的话，请各位帮帮我。

这是CSS styles.css：

#cssmenu ul,
#cssmenu li,
#cssmenu span,
#cssmenu a {
  margin: 0;
  padding: 0;
  position: relative;
}
#cssmenu:after,
#cssmenu ul:after {
  content: '';
  display: block;
  clear: both;
}
#cssmenu a {
  color: #333333;
  display: inline-block;
  font-family: 'Lucida Grande', 'Lucida Sans Unicode', Helvetica, Arial, Verdana, sans-serif;
  font-size: 12px;
  min-width: 35px;
  text-align: center;
  text-decoration: none;
  text-shadow: 0 -1px 0 #eeeeee;
}
#cssmenu ul {
  list-style: none;
}
#cssmenu > ul > li {
  float: left;
}
#cssmenu > ul > li.active a {
  background: #d9d9d9 url(images/grad_light.png) repeat-x left bottom;
  background: -moz-linear-gradient(top, #d9d9d9 0%, #bfbfbf 100%);

  padding: 9px 5px;

}

这是HTML

<head>
<link href="styles.css" rel="stylesheet" type="text/css">
</head>

<body>
<div id='cssmenu'>
<ul>
   <li class='active '><a href='index.html'><span>Home</span></a></li>
   <li class='has-sub '><a href='#'><span>Products</span></a>
      <ul>
         <li><a href='#'><span>Product 1</span></a></li>
         <li><a href='#'><span>Product 2</span></a></li>
      </ul>
   </li>
   <li><a href='#'><span>About</span></a></li>
   <li><a href='#'><span>Contact</span></a></li>
</ul>
</div>
</body>

通常你必须展示你尝试过的一些工作。但我猜你对css的含义一无所知。

你只需要修改你的css，在你的css后添加：

#cssmenu ul {
  width:200px;
}

#cssmenu > ul > li {
  float: none;
}
#cssmenu .has-sub ul {
  top: -1px;
  left: 200px;
}
#cssmenu a {
  display: block;
}

#cssmenu .has-sub ul li a {
  border-top: 1px solid #d2d2d2;
}

请记住，HTML只包含内容，而不是样式。这意味着你可以删除CSS并只留下一个无序列表，这对于任何类型的菜单都是很好的语义标记。从那里，使用新的CSS将其构建为垂直菜单，或任何真正的。如果你愿意，你可以按照CSS教程制作你想要的菜单类型，因为任何教程都应该从看起来与你的类似的HTML开始。

（虽然我们正在讨论语义，但我应该指出所有span和包装div都是不必要的，并且可以在没有它们的情况下创建工作菜单。）

请帮助将水平css下拉菜单更改为垂直下拉菜单
