伪元素:在chrome mobile

我有一个带有导航元素的页面,我想隐藏在页面的左/右边,并在我悬停图标时显示。我在我想隐藏的元素上使用:after伪元素创建了图标。该解决方案在经过测试的桌面浏览器上运行良好但在chrome mobile上失败(即使桌面版本工作正常)。

我在iOS和Android上都进行了测试,没有人能够显示:after伪元素。 但是如果您碰巧点击:after应该在的位置,菜单会显示。所以它似乎只是一个显示问题。

我已创建this jsfiddle来显示问题。我添加了一些javascript只是因为它在真实页面上,但我不认为这是问题的原因。

甚至更奇怪的是,在iOS上,chrome和safari都可以在jsfiddle上显示MS,但无法在真实页面上显示图标。但Android上的Chrome也无法在jsfiddle上显示元素。

所以,我的问题是,如何在Chrome移动版或iOS浏览器上显示:after个伪元素?

不确定移动浏览器会发生什么,但从overflow-y: auto;header nav移除header aside似乎无效。

但是,如果您确实需要滚动条,则可以在<ul>中添加其他元素(即<nav>)。

header nav ul {
  position: absolute;
  top: 0; bottom: 0; left: 0; right: 0;
  padding: 0;
  margin: 0;
  overflow-y: auto;
}
