html - 文本叠加隐藏在旁边的图像后面

Question

我正在尝试在陪审团图像之上创建文本叠加层，但我的文本叠加层似乎隐藏在它旁边或第二行下方的图像后面。理想情况下，我想让叠加层更大，但我遇到了这个问题。见截图。有什么我应该添加到代码或更改的吗？

Answer 1

如果您希望叠加层出现在其他图像之上，您还需要设置叠加层的 z-index。

此处示例 http://codepen.io/anon/pen/doQjZG?editors=110

ul.img-list li:hover span.text-content {
  opacity: 99;
  z-index: 99;
}

此外，切勿将不透明度或 z-index 设置得高于绝对必要的值。如果您希望元素取代这些值，这可能会在以后导致问题。
