问题描述

我制作了一个CSS幻灯片演示,其中包含3个由关键帧动画的图像,从而产生淡入/淡出效果.到目前为止,一切顺利.但是幻灯片第二个循环中的动画存在问题.

I made an CSS slideshow with 3 images animated by keyframes that makes a fade in/out effect. So far, so well. But there's a problem with the animation on the second loop of the slideshow.

我要解释我的最好的情况:第一个循环动画效果很好,但是一旦第一个图像再次出现,我想避免的所有幻灯片都会变成白色.

Im going to explain my best: the first loop animation works perfectly, but once the first image come back again there's a fade to white on all the slides that I like to avoid.

我不明白为什么第一个循环会完美运行,然后其他循环会逐渐淡化为白色.您可以在代码段中看到此问题.

I don't understand why the first loop works perfectly and then the other loops have this fade to white issue. You can see this problem on the Snippet.

真的很感谢您!
