Question

我更新了微软徽标的animation。它可以在CodePen上找到。总的来说，除了一件事，我现在非常满意。

我似乎无法弄清楚如何停止动画以使徽标看起来正确。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制作YouTube视频，比如文字何时出现？谢谢！

var playState = '-webkit-animation-play-state';

$(".boxes").css(playState, "running");
setTimeout(function() {
  $(".boxes").css(playState, "paused");
}, 5900);

不是使用jQuery / JavaScript来停止动画，更好的方法是为每个以你想要的位置结束的方框指定不同的动画。

Example CodePen

至于在文字出现时播放YouTube视频，如果您参考YouTube API Docs，jQuery会是这样的：

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
