CSS 3 Animation with Keyframes on hover change of opacity and z-index不起作用

Question

我有一些动人的文字css3动画。 动画很好（sn-p）。如果有人使用悬停，动画会停止（很好），但不接受不透明度和 z-index 的更改（.bubble:hover）。

    opacity: 1;
    z-index: 100;

.bubble:hover 类正在使用中，转换动作有效。

transform: scale(1.2);

目的是在前景中弹出悬停的气泡。 如果气泡离开，动画应该从停止点继续移动。 我该如何解决？

感谢您的帮助。

Answer 1

这发生的原因是您使用“颜色”关键帧为父 div 提供了较少的不透明度，然后将该动画应用于悬停 div 的父级。您应该对“气泡”div 进行颜色更改。
