transform：rotate（-90deg）无法在iPhone上运行

Question

我创建了这个动画图，但由于某种原因，路径的起点为90deg，所以我在其上放置了一个变换：rotate（-90deg）从0deg开始。这在Chrome和Safari中的桌面上工作正常，但是当我在iPhone上查看时，它似乎忽略了我的旋转并返回到默认的90deg起点。我尝试过一堆前缀而没有任何变化。

Here's the link on CodePen

body {
  background-color: #34495e;
}

.skills-graph {
	fill: transparent;
  transform: rotate(-90deg);
	-webkit-transform: rotate(-90deg);
	-ms-transform: rotate(-90deg);
	-moz-transform: rotate(-90deg);
	-o-transform: rotate(-90deg);
	position: absolute;
	top: 0px;
  right: 0px;
  bottom: 0px;
  left: 0px;
  margin: auto;
}

Answer 1

我没有答案，但是我在iPhone 6s（safari）上使用了codepen代码片段，当我更改了＆＃34; -webkit-transform：rotate（-90deg）;＆＃34时; （在.skills-graph中）到＆＃34; -webkit-transform：rotate（170deg）;＆＃34;它改变方向。也许你现在可以自己找到答案。 （我对代码不太好）。祝你好运！

编辑：使用＆＃34; -webkit-transform：rotate（-89deg）;＆＃34;看来是对的。
