它渲染div与所有的css(e。G球半径和背景颜色等)，但关键帧(即:过渡/移动)的球不工作到一段时间(直到所有的css/js下载和解析)，但之后它工作得很好。
我认为可能是在加载和解析css/js渲染引擎会很忙，所以它不能执行过渡，但当我看了看其他网页，他们使用css加载器，因为我做的，它工作得很好。所以当我的动画不工作时，他们的动画是如何工作的。
因为浏览器选项卡是单线程的。有些浏览器完全是单线程的。
如果JavaScript在某些浏览器中从未停止运行，你甚至不能关闭选项卡。
如果你想要DOM重新绘制，或者画布动画，或者页面是可点击的，你可以而不是锁定JS。这意味着您必须学习不同的编程范例来分解长时间运行的流程。
