CSS 文本在正弦波动画上飞行答案

【问题标题】：CSS text flying on a sine wave animationCSS 文本在正弦波动画上飞行

【问题描述】：

我正在做一个文本漂浮在正弦波旋转的波浪上的动画。我得到了正弦曲线本身。但是我在平滑旋转文本中的字母以使它们平滑地相互跟随时卡住了，如下面的示例所示。文字本身上下浮动，转动时字母转动不顺畅。告诉我如何实现正确的字母轮换。

这种动画取决于屏幕宽度，所以在全屏页面运行以获得更好的效果：

要自定义宽度更小的动画，只需更改时间：从右到左飞行16s线性无限，曲线8s缓入无限，曲线旋转8sease-in-out 无限

如果你想改变字母之间的空间：改变动画延迟每个孩子.text-anim:nth-child()
