CSS：悬停在实践中不工作
问题描述：
我正在一个个人设计项目中，我有5个图像在他们的瓷砖，当你将鼠标放在任何一个他们显示替代文字。我已经包含了我的源代码，但我的问题似乎是当我通过在tile上悬停来测试这个问题时，我添加了W3代码片段而没有发生任何事情。如果我检查代码，然后在Chrome检查工具中添加悬停属性，它似乎工作得很好。我在这里错过了什么？CSS：悬停在实践中不工作

这是与其他瓷砖重叠的容器问题（z-index问题）。你可以尝试这样的事情：
.tiles {
pointer-events: none;
}
.container {
pointer-events: auto;
}
+0
这将是一个快速修复。我会建议你重构你的代码，以便元素不重叠。 – JRoss

尽管这在识别问题时是正确的，但我没有测试您发送的代码，因为我可以通过调整z-index值将底部拼贴块放在顶部拼贴块下方来解决问题。 –

这是因为使用了.tiles类被认为是2行的图片都.COL-XS-12项目。
.tiles类具有顶部，左侧的属性定义和位置属性为绝对。由于这两行图片的顶部和左侧位置都与.tiles相同，因此第二个图片与第一个图片重叠。
这就是为什么悬停永远不会发生.container通常。悬停总是发生在第二排，尽管第一排在下面可见，但仍位于顶部。
请在这里发表代码，我甚至不能说出哪个元素悬停被认为是对 – Huangism
你不是有一个叫'类随时随地overlay'，更遑论'.container'的后代@ – TylerH
@TylerH叠加在那里，它只是被其他元素所覆盖。所以当你将鼠标悬停在第一块瓷砖上并进行检查时，你会落在其他元素上。问题与如何布置页面 – Huangism
