双向无限图像滑块

问题描述

我希望在相反方向上无限滚动。我已经成功地制作了一个，但另一个有一些小故障，因为它在顶部显示额外的空白并且不能正确滚动。我曾尝试更改 css 动画，但无法做到。请参考下面的代码。

@-webkit-keyframes scroll {
  0% {
    transform: translateY(0);
  }
  100% {
    transform: translateY(calc(-50vh * 3));
  }
}

@keyframes scroll {
  0% {
    transform: translateY(0);
  }
  100% {
    transform: translateY(calc(-50vh * 3));
  }
}

@-webkit-keyframes rev-scroll {
  0% {
    transform: translateY(0);
  }
  100% {
    transform: translateY(calc(100vh * 3));
  }
}

@keyframes rev-scroll {
  0% {
    transform: translateY(0);
  }
  100% {
    transform: translateY(calc(100vh * 3));
  }
}
.sliderr {
  background: white;
  Box-shadow: 0 10px 20px -5px rgba(0,0.125);
  height: 100vh;
  /* margin: auto; */
  overflow: hidden;
  position: relative;
  width: 30vw;
  padding: 0 !important;
}
.sliderr::before,.sliderr::after {
  background: linear-gradient(to top,rgba(0,1) 0%,rgba(255,255,0) 100%);
  content: "";
  height: 25vh;
  position: absolute;
  width: 30vw;
  z-index: 2;
}
.sliderr::after {
  /* right: 0; */
  top: 0;
  left: 0;
  transform: rotateZ(180deg);
}
.sliderr::before {
  left: 0;
  bottom: 0;
}
.sliderr .slide-track {
  -webkit-animation: scroll 40s linear infinite;
          animation: scroll 5s linear infinite;
  display: flex;
  flex-direction: column;
  height: calc(50vh * 6);
}
.sliderr .slide {
  height: 50vh;
  width: 30vw;
}

.sliderr .slide img{
  height: 50vh;
  width: 30vw;
  object-fit: cover;
}

.sliderr .slide-track-rev {
  -webkit-animation: rev-scroll 40s linear infinite;
          animation: rev-scroll 5s linear infinite;
  display: flex;
  flex-direction: column;
  height: calc(50vh * 6);
