我的 html/css 代码干扰了我的HTML/CSS下拉菜单

我的导航栏上方有一个文本框，但我的 CSS 下拉菜单担心 CSS 代码。

看起来您遇到了分层问题 - 输入字段周围的框实际上扩展了整个屏幕宽度并且位于菜单前面，因此您无法“进入”菜单。

容易修复，只需设置一个宽度#advsearch并给它一个更高的z-index. 像这样：

#advsearch {
    text-align: center;
    margin: 20px auto 0px;
    width:250px;
    position:relative;
    z-index:100;
}

#cssmenu我还向（我使用了）添加了高于 -1 的 z-index，z-index:50;因为 -1 使菜单在大多数浏览器上无法使用。

已更新您的 jsfiddle。请参阅更新的 JSFiddle

代码更改。添加margin-left: 50px;到#advsearch

#advsearch {
    text-align: right;
    margin-left: 50px;
    margin-top: 20px;
}

首先正确关闭你的html标签。

你错过了 li 和 ul 结束标签。

</li>
</ul>

在标签之前关闭它

更改以下 css: (添加 padding-top:20px; )

#cssmenu {  position:fixed; left: 0; 
  padding-top:25px; 
  top: 0; width: 100%; z-index:-1;
}
