html - CSS 微调器序列在 iOS Chrome 中运行不流畅？

Question

我有一个 CSS 微调器，可以在除 iOS Chrome 之外的任何地方使用。在 iOS Chrome 中，动画非常不稳定，破坏了预期的平滑序列。这是我目前的代码:

HTML

<div class="spinner">
    <span class="child1"></span>
    <span class="child2"></span>
    <span class="child3"></span>
    <span class="child4"></span>
    <span class="child5"></span>
    <span class="child6"></span>
    <span class="child7"></span>
    <span class="child8"></span>
</div>

CSS

@keyframes loader {
  0% {
      background-color: #ffffff;
  }
  100% {
      background-color: transparent;
  }
}
.spinner {
    border-radius: 100px;
    height: 100px;
    position: relative;
    transform: scale(0.6);
    width: 100px;
}
.spinner span {
    animation-direction: normal;
    animation-duration: 1.04s;
    animation-iteration-count: infinite;
    animation-name: loader;
    background: transparent none repeat scroll 0 0;
    border-radius: 50px;
    display: inline-block;
    height: 16px;
    position: absolute;
    width: 16px;
}
.spinner span.child1 {
    animation-delay: 0.39s;
    left: 50%;
    margin-left: -8px;
    top: 0;
}
.spinner span.child2 {
    animation-delay: 0.52s;
    left: 71px;
    top: 13px;
}
.spinner span.child3 {
    animation-delay: 0.65s;
    margin-top: -8px;
    right: 0;
    top: 50%;
}
.spinner span.child4 {
    animation-delay: 0.78s;
    left: 71px;
    top: 72px;
}
.spinner span.child5 {
    animation-delay: 0.91s;
    bottom: 0;
    left: 50%;
    margin-left: -8px;
}
.spinner span.child6 {
    animation-delay: 1.04s;
    left: 13px;
    top: 72px;
}
.spinner span.child7 {
    animation-delay: 1.17s;
    left: 0;
    margin-top: -8px;
    top: 50%;
}
.spinner span.child8 {
    animation-delay: 1.3s;
    left: 13px;
    top: 13px;
}

我还有所有的 CSS 前缀 -webkit-, -o-, -ms-...如果有人能阐明我哪里出错了，那就太好了。

我想通了!我在页面上同时关闭了 2 个动画，这导致了延迟。另见:http://chrissilich.com/blog/fix-css-animation-slow-or-choppy-in-mobile-browsers/
