使用Jquery响应下拉导航

标签: jquery html

我是Jquery的新手。 我正在尝试构建响应式网站,因此从Navigation Part开始。 我为导航编写了一些代码并且它的工作很好并且导航具有嵌套项目。但问题是,无论何时调整窗口大小,导航都会折叠为“菜单”导航按钮,当我单击导航项时它重叠其他导航项目。 每当我选择不同的导航项时,所选的导航项也不会关闭。

将您的CSS更改为此 - 我所做的就是将absolute位置更改为relative,并为菜单指定固定宽度,您当然可以更改:

html {
  font-family: sans-serif;
  -webkit-text-size-adjust: 100%;
  -ms-text-size-adjust: 100%;
}

* {
  margin: 0px;
