android - 伪元素 :after disapears on chrome mobile
<p><p>我有一个带有导航元素的页面，我希望将其隐藏在页面的左侧/右侧，并在我悬停图标时显示。我在要隐藏的元素上使用 <code>:after</code> 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 移动设备上失败(即使桌面版本运行良好)。</p>
<p>我在 iOS 和 Android 上都进行了测试，没有一个能够显示 <code>:after</code> 伪元素。 <strong>但是</strong>如果你碰巧点击了 <code>:after</code> 应该在的位置，菜单就会显示出来。所以看起来这只是一个显示问题。</p>
<p>我创建了<a href="https://jsfiddle.net/yr4zag6n/4/" rel="noreferrer noopener nofollow">this jsfiddle</a>显示问题。我添加了一些 javascript 只是因为它在真实页面上，但我认为这不是问题的原因。</p>
<p>更奇怪的是，在 iOS 上，chrome 和 safari 都可以在 jsfiddle 上显示 <code>M</code> 和 <code>S</code> 却无法在真实页面上显示图标。不过，Android 上的 Chrome 也无法在 jsfiddle 上显示元素。</p>
<p>那么，我的问题是，如何在 Chrome 移动或 iOS 浏览器上显示 <code>:after</code> 伪元素？</p>

<p><p>不确定移动浏览器发生了什么，但似乎从 <code>header nav</code> 和 <code>header side</code> 中删除 <code>overflow-y: auto;</code>工作。</p>
<p>但是，如果您确实需要滚动条，您可以在 <code><nav></code> 中添加另一个元素(即 <code><ul></code>)。</p>
<pre><code>header nav ul {
position: absolute;
top: 0; bottom: 0; left: 0; right: 0;
padding: 0;
margin: 0;
overflow-y: auto;
}
</code></pre>
