Question

我想使用css动画从右到左滑动一些对象。我希望页面顶部的高度是随机的，动画的速度也是随机的。我已经设法通过使用JavaScript来做到这一点。问题是对象随机地刷新＆＃34;或者全面跳转。我尝试了很多不同的方法，看看是不是我，但我找不到问题。
我希望的最终结果是这个网站的背景。 https://realtimebitcoin.info/

这是我的代码。

谢谢

编辑：我忘了提到这只适用于Chrome现在

Answer 1

我没有看到你提到的问题。由于左侧属性的动画，这可能是一个性能问题。

您应该仅使用left和top属性随机化框的第一个位置，然后使用

left: -150px

而不是

multiselect()

将它们移到左侧。

更改动画中的左侧或顶部属性会导致大量浏览器重新绘制。您可以使用＆＃34;油漆闪烁＆＃34;自己检查它。在chrome dev工具中的渲染选项卡上标记。

使对象从右向左滑动
