我需要一些有关暂停和恢复动画的帮助。有没有办法在几秒钟后暂停 attritubeName =“ offset” 然后反转偏移量？
基本上，梯度向右偏移，然后在几秒钟后暂停，然后向左偏移……以几个间隔。
我能够使用 animate （动画）来反转值，但是它需要暂停几个时间间隔。我不确定使用 keyTimes 是否可以解决此问题，因为间歇间隔很长。
可以在这里找到带有svg渐变的反向动画的演示：https://codepen.io/tfss/pen/BbOYmx 以及这里：https://jsfiddle.net/telosantos/vreqL6bd/24/
这是渐变动画的代码段，我希望间隔为：
