悬停效果链接

Question

我正在使用 CSS 悬停效果，即剥离粘性 (http://www.designrazor.net/30-pure-css3-image-hover-effects/)。我想尝试在后面的圆圈中放一个链接。

但我的问题是链接不可点击。谁能帮我看看是什么问题？我认为这是因为课程，但我不知道我必须更改或放入 CSS 中。

您遇到的问题是，尽管divs 看起来不像，但它们包含在盒子中。这些框是透明的并堆叠在链接的顶部。要使链接可点击，您需要使用z-index 修改堆叠顺序：

• 添加新规则#Awesome a，内容如下：
  • position: relative; - 使 z-index 工作
  • transition: z-index 0s; - 将确保当元素未悬停时，从 z-index: 1; 到 z-index: 0; 的转换是即时的
  • z-index: 0; - 默认情况下会将链接放在其他元素的后面
• 添加新规则#Awesome:hover a，内容如下：
  • transition: z-index 1s ease-in-out; - 将确保动画结束时链接堆叠在其他元素之上
  • z-index: 1; - 将链接置于其他元素之上
