Question

我对动画延迟有疑问。我有一个6个图像的列表，所以我想创建一个自动滑动旋转木马效果。所以我已经让他们完成了CSS动画的翻译。但是，图像运行的时间计算不充分，因此，在查看图像时，图像会短暂重叠。我想要实现的是使图像不重叠并平滑地循环运行。我创造了一个小提琴。

.banner ul {
  list-style: none;
  margin: 0;
  padding: 0;
  width: 300px;
  height: 200px;
  display: inline-block;
  position: relative;
}

 .banner ul li {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  animation: coverflow 9.5s ease infinite;
}

  .banner ul li:nth-child(2) {
  animation-delay: 1.5s;
}
 .banner ul li:nth-child(3) {
  animation-delay: 3s;
}
 .banner ul li:nth-child(4) {
  animation-delay: 4.5s;
}
 .banner ul li:nth-child(5) {
  animation-delay: 6s;
}
 .banner ul li:nth-child(6) {
  animation-delay: 7.5s;
}
 .banner ul li:nth-child(7) {
  animation-delay: 9s;
}

 .banner ul li img {
  width: 100%;
  height: 100%;
}


@keyframes 
coverflow {  
0%, 10% {
 opacity: 1;
 transform: none;
 z-index: 10;
}
 25%, 35% {
 opacity: 0.2;
 transform: translate3d(-170px, 0, 0) scale(0.6);
}
 50% {
 opacity: 0;
 transform: translate3d(-190px, 0, 0) scale(0.6);
}
 60% {
 opacity: 0;
 transform: translate3d(190px, 0, 0) scale(0.6);
}
 75%, 85% {
 opacity: 0.2;
 transform: translate3d(170px, 0, 0) scale(0.6);
}
}

非常感谢你。

你可以试试这个：

我让动画从新状态开始以避免重叠。我还将持续时间修改为 9s ，以便每次都保持相同的周期。

.banner {
  text-align: center;
}

.banner ul {
  list-style: none;
  margin: 0;
  padding: 0;
  width: 300px;
  height: 200px;
  display: inline-block;
  position: relative;
}

.banner ul li {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  animation: coverflow 9s ease infinite;
  opacity: 0.2;
  z-index: -1;
  transform: translate3d(170px, 0, 0) scale(0.6);
}

.banner ul li:nth-child(2) {
  animation-delay: 1.5s;
}

.banner ul li:nth-child(3) {
  animation-delay: 3s;
}

.banner ul li:nth-child(4) {
  animation-delay: 4.5s;
}

.banner ul li:nth-child(5) {
  animation-delay: 6s;
}

.banner ul li:nth-child(6) {
  animation-delay: 7.5s;
}

.banner ul li:nth-child(7) {
  animation-delay: 9s;
}

.banner ul li img {
  width: 100%;
  height: 100%;
}

@keyframes coverflow {
  0%,
  10% {
    opacity: 0.2;
    z-index: -1;
    transform: translate3d(170px, 0, 0) scale(0.6);
  }
  10%,
  25% {
    opacity: 1;
    transform: none;
  }
  25%,
  45% {
    opacity: 0.2;
    z-index: -1;
    transform: translate3d(-170px, 0, 0) scale(0.6);
  }
  60% {
    opacity: 0;
    z-index: -1;
    transform: translate3d(-190px, 0, 0) scale(0.6);
  }
  70% {
    opacity: 0;
    z-index: -1;
    transform: translate3d(190px, 0, 0) scale(0.6);
  }
}
