CSS关键帧动画和延迟？ [英] CSS keyframe animations and delay?

问题描述

我有一个关键帧动画，无限循环。

I have a keyframe animation, that infinitly loops.

-webkit-animation: fade 3s ease-in-out infinite;

@-webkit-keyframes fade {
0% { opacity: 0; -webkit-transform: rotate(0deg);}
20% { opacity: 1; -webkit-transform: rotate(360deg);}
100% { opacity: 0; -webkit-transform: rotate(360deg);}
}

如何延迟每个循环的过滤。我知道我可以延迟整个动画，但这只会发生一次。我希望每次都这样做。

How can I delay each ilteration of the loop. im aware I can delay teh entire animation, but this only occurs once. I wish to do it everytime.

推荐答案

不幸的是，当前没有选项可以轻松地在迭代之间设置延迟，但是您可以可以添加具有相同值的另一个止损（如我所评论），并增加持续时间：

Unfortunately there is no current option to easily put a delay between the iterations, but instead you can add another stop with the same values (as I commented), and increase the duration:

@keyframes fade {
    0% { opacity: 0; transform: rotate(0deg); }
    10% { opacity: 1; transform: rotate(360deg); }
    50% { opacity: 0; transform: rotate(360deg); }
    100% { opacity: 0; transform: rotate(360deg); }
}

.selector {
    animation: fade 6s ease-in-out infinite; /* increased duration */
}

如果需要通过脚本控制何时需要重新启动动画，可以查看： http：// css-tricks.com/restart-css-animation/
