全屏图像滑块在花费时间后重复

Question

sudo systemctl status php7.1-fpm.service

.slideshow {
  position: fixed;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: 0;
  list-style: none;
  margin: 0;
  padding: 0;
}

.slideshow li {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  background-size: cover;
  background-position: 50% 50%;
  background-repeat: none;
  opacity: 0;
  z-index: 0;
  animation: imageAnimation 60s linear infinite;
}

.slideshow li:nth-child(1) {
  background-image: url("https://www.w3schools.com/howto/img_fjords.jpg")
}

.slideshow li:nth-child(2) {
  background-image: url("https://cloud.netlifyusercontent.com/assets/344dbf88-fdf9-42bb-adb4-46f01eedd629/68dd54ca-60cf-4ef7-898b-26d7cbe48ec7/10-dithering-opt.jpg");
  animation-delay: 10s;
}

.slideshow li:nth-child(3) {
  background-image: url("https://cdn.pixabay.com/photo/2016/06/18/17/42/image-1465348_1280.jpg");
  animation-delay: 20s;
}

.slideshow li:nth-child(4) {
  background-image: url("http://eskipaper.com/images/image-2.jpg");
  animation-delay: 30s;
}

@keyframes imageAnimation {
  0% {
    opacity: 0;
    animation-timing-function: ease-in;
  }
  10% {
    opacity: 1;
    animation-timing-function: ease-out;
  }
  20% {
    opacity: 1
  }
  30% {
    opacity: 0
  }
}

.no-cssanimations .slideshow li {
  opacity: 1;
}

我附加了我的CSS和HTML代码。 5.jpeg显示后，显示一个空白页面，然后滑块重新开始重复。我想有一个连续重复的图像幻灯片，没有中断。我的代码可能有一些错误。因为我是网页设计的新手请帮帮我。 谢谢

.slideshow li{
    animation: imageAnimation 40s linear infinite;
}

如您所见，我将60s更改为40s，这是导致临时白色背景的原因。

<强>更新

我们可以看到第二个animation-delay在10s后开始，在20s后第3个和30s后第4个开始。

如果animation中的总时间为60s，那么对于第4个动画，事务的总持续时间为30s，即从第30秒到第60秒。

这就是为什么你在第4张照片后得到白屏。
