CSS 动画不适用于移动设备

Question

我目前正在为一个移动网站开发侧边栏导航，我正在尝试为主菜单按钮添加以下动画。

除运行 iOS - Safari 和 Android - Android 浏览器的移动设备外，这适用于不同的浏览器。我错过了什么？谢谢。

您好，我试过您的 fiddle ，它在我的手机(iphone5s)上运行良好。但无论如何，据我所知，当您想对元素使用关键帧转换时。元素必须是显示 block ，或者必须由 div 包裹，默认也是显示 block 。

a { 
  background:orange;
}
div {
  -webkit-animation: move 5s infinite;
}

@-webkit-keyframes move {
  0% { -webkit-transform: translate(20px); }
  100% { -webkit-transform: translate(500px); }
}

<div class="wrapper"><a href="#">Test</a></div>

我在想也许 translate 不完全支持某些元素。例如，当你想翻译标签元素时，你必须设置元素display: block。

但是，当您想在 div 元素上应用翻译时，如果您在 div 元素上设置 css display:inline-block，翻译仍然会在该 div 上工作。

所以也许可以尝试设置您想要移动的元素 display:block。
