我更新了我的animation微软徽标.它在CodePen上可用.总的来说,除了一件事,我现在对它非常满意.

我似乎无法弄清楚如何停止动画,所以徽标看起来正确.我尝试将延迟设置为6000ms = 6s =动画的长度,但它看起来很偏僻.现在它设置为5900ms.关于这个的任何提示？

我想知道的另一件事是,在一段时间之后你会如何播放YouTube视频,比如文字何时出现？谢谢！

解决方法:

而不是使用jQuery / JavaScript来停止动画,更好的方法是为每个盒子指定一个不同的动画,以你想要的位置结束它们.

Example CodePen

至于在文本出现时播放YouTube视频,如果您参考YouTube API Docs,jQuery中就会出现这样的情况：

setTimeout(function(){
    //play the youtube video (#playerId) is the id of your youtube video element
    $('#playerId').get(0).playVideo();
} , 4500); //4500 is the delay in ms
