如您所见，它运行良好，动画快速流畅。

但是，当我添加一些图像时：http://jsfiddle.net/xs4mm5jd/1/ 动画有问题。有没有什么办法可以加快性能？

Answer 1

即使我没有看到您的小提琴性能不佳，您也可以在制作动画时触发硬件加速。

有些人使用一种技巧，将transform: translateZ(0); 或transform: translate3d(0, 0, 0); 应用于动画元素。

如果你看到任何性能提升，你可以在这里测试一下：http://jsfiddle.net/gleezer/xs4mm5jd/3/

这是一个关于它的article。

第二个更新（可能更好）的替代方法是在 CSS 中使用 will-change 属性，例如：will-change: transform;
