这是一个类似 Facebook 的加载器。我不知道为什么这是闪烁的。
我试过改变大小，这会影响闪烁，但我不明白如何。
有人可以帮我弄清楚为什么吗？

div{
width:600px;
height:100px;
}

.placeholder-waves {
    -webkit-animation-duration: 1.3s;
    animation-duration: 1.3s;
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
    -webkit-animation-name: wave;
    animation-name: wave;

    background-size: 1200px 104px;
    background: #f6fbfb;
    background: #eeeeee;
    background: linear-gradient(to right, #eeeeee 4%, #dddddd 47%, #eeeeee 87%);
}

@keyframes wave {
  0% {
    background-position: -468px 0
  }
  100% {
    background-position: 468px 0
  }
}

@-webkit-keyframes wave {
  0% {
    background-position: -468px 0
  }
  100% {
    background-position: 468px 0
  }
}

<div class="placeholder-waves"></div>

Answer 1

在关键帧中，您写道:background-position: -468px 0;
是否有理由使用 468px当你的 div 的长度是 600px 时？因为这就是跳跃的原因。由于 div，渐变为 600px 长。所以在任何地方都使用相同的长度( 600px )，它工作得很好:

div{
width:600px;
height:100px;
}

.placeholder-waves {
    -webkit-animation-duration: 1.3s;
    animation-duration: 1.3s;
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;
    -webkit-animation-iteration-count: infinite;
    animation-iteration-count: infinite;
    -webkit-animation-name: wave;
    animation-name: wave;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;
    -webkit-animation-delay: 0s;
    animation-delay: 0s;
    -webkit-animation-direction: normal;
    animation-direction: normal;
    background-size: 1200px 104px;
    background: #f6fbfb;
    background: #eeeeee;
    background: linear-gradient(to right, #eeeeee 4%, #dddddd 47%, #eeeeee 87%);
}

@keyframes wave {
  0% {
    background-position: -600px 0
  }
  100% {
    background-position: 600px 0
  }
}

@-webkit-keyframes wave {
  0% {
    background-position: -600px 0
  }
  100% {
    background-position: 600px 0
  }
}

<div class="placeholder-waves"></div>
