＆＃13;

我想知道它是否可以更好地完成（阅读：更聪明的方式）。我花了一些时间来计算和准备所有的动画步骤（使用excell），我觉得很愚蠢。

第二个问题（基于其中一个评论）是否这个动画可以更顺畅？怎么做到了？

Answer 1

以下是使用答案中提到的 jcaron 方法的示例。您只需使用水平线的副本并将它们放在一起，即第一个元素之前的最后一个元素。父元素的宽度必须是hr元素之一的两倍。然后，您可以轻松地为父元素设置动画，而不必在动画中重绘线性渐变。

＆＃13;

@keyframes hr-animation {
  from{ transform: translate(0, 0); }
  to{ transform: translate(50%, 0); }
}
@-webkit-keyframes hr-animation {
  from{ -webkit-transform: translate(0, 0); }
  to{ -webkit-transform: translate(50%, 0); }
}
.hr-animation {
  -webkit-animation: hr-animation 5s linear infinite;
  animation: hr-animation 5s linear infinite;
}

body {
  margin: 10px 0 0 0;

Answer 2

保持你的结构最大化，这是我的解决方案

.colored {
  margin-top: 5px;
  margin-bottom: 5px;
  height: 7px;
  border-top: 0;
  background: #c4e17f;
  border-radius: 5px;
  background-image: linear-gradient(to right, #c4e17f, #c4e17f 12.5%, #f7fdca 12.5%, #f7fdca 25%, #fecf71 25%, #fecf71 37.5%, #f0776c 37.5%, #f0776c 50%, #db9dbe 50%, #db9dbe 62.5%, #c49cde 62.5%, #c49cde 75%, #669ae1 75%, #669ae1 87.5%, #62c2e4 87.5%, #62c2e4);
  padding-right: 50%;
  background-origin: content-box;
  background-size: 200%;
  animation-name: colored;
  animation-duration: 2s;
  animation-iteration-count: infinite;
  animation-timing-function: steps(8);
}

@keyframes colored {
  from {background-position: 0% 0%;}  
    to {background-position: 200% 0%;}
}

<hr class="colored">

我使用步进功能设置背景位置的动画，因此可以轻松实现颜色的离散变化。

使用单个渐变，响应和动画可能有点棘手。

最简单的解决方案，即背景大小为100％，不受背景位置变化百分比的影响。

诀窍是只在元素的一半上设置背景（使用填充技巧实现），然后将尺寸设置为200％

Answer 3

一种选择是使用两个元素，一个包含另一个元素。

外面的那个将具有你想要的实际尺寸和位置。内部的一个是大小的两倍，梯度重复两次。外部元素将具有溢出：隐藏以掩盖超出其边界的任何内容。

然后，您可以设置内部元素相对于外部元素的位置。
