我的环境(哪里有问题):

动画:
情况:
我在谷歌上搜索了很多,但没有找到对我有用的东西。我知道以前有人问过这个问题。
当我用 Safari 和 Firefox 打开网站时,CSS3 动画在我的 Mac 上很流畅,但在 Chrome 上却不行!
奇怪的是,原来的 CodePen 在 Chrome 上很流畅。
问题:
我的代码中的某些内容导致动画仅在 Chrome 上不稳定。这是什么,我该如何解决?
我看到了什么:
我需要相对定位以适应不同的屏幕尺寸。

我唯一添加到 CodePen 的东西:
.marquee ul li a{

.marquee ul li a img {

}
删除它并不能解决问题。

我似乎刚刚在我的动画中发现了一个奇怪的行为。每次我移出视线并通过滚动返回时,它都会“增长”(变大)。
这种行为似乎是上述问题的答案中所描述的。但是像建议的那样指定固定宽度并不能解决滞后问题。

这很奇怪。在注释和取消注释某些行之后(基本上回到有延迟时的代码),动画性能变得更好。不如在 Safari 或 Firefox 中流畅,但仍然流畅。

我找到了“罪魁祸首”。
我在我网站的标题中使用了另一个代码笔:

<link href='http://fonts.googleapis.com/css?family=Lato:300,400,700' rel='stylesheet' type='text/css'>

删除它会使其他动画平滑。
尽管如此:
这并不能解释为什么在 Firefox 和 Safari 中一切都很顺利,但在 Chrome 中却不行。
Chrome 功能是否较弱?
我向 Chrome 提交了一份报告,希望他们会在这里回答,但不能保证。
如果有人可以从 Google / Chrome 中得到答案,我会奖励他/她。

在 Opera 浏览器上试过。完全一样的滞后!现在我们知道这是 BLINK 渲染引擎的问题!
