我正在尝试使用 CSS 和 SVG 创建一个简单的动画:旋转齿轮。动画在 Chrome 但不是 Firefox 中完美运行。这是实际代码:http: //jsfiddle.net/fL8Qn/
齿轮是 SVG 文件中的路径:
<div class="svg">
<svg x="0px" y="0px" width="200" height="200" viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<title>PDP</title>
<text x="44" y="120" class="gear_text">PDP</text>
<g transform="translate(50%, 50%)">

动画是使用 CSS 应用的:
.svg {
width:200px;
height:200px;
float:left;
position: fixed;
top: 20px;
left: 50px;
}
.go-clockwise {
-webkit-animation: clockwise 3s infinite linear;
-moz-animation: clockwise 3s infinite linear;
}
.go-counter-clockwise {
-webkit-animation: counter-clockwise 3s infinite linear;
-moz-animation: counter-clockwise 3s infinite linear;
}
path.gear{
fill: #3f3f3f;
}
text.gear_text{
font-size: 55px;
font-weight: 900;
fill: #3f3f3f;
}

使用 CSS 是首选方法,因为我正在动态应用该类。(向下滚动时逆时针,向上滚动时顺时针)但出于这个问题的目的,我只是应用一个类。Chrome 可以很好地渲染它,但 Firefox 似乎没有使用-moz-transform-origin属性。无论我使用什么,firefox 似乎都在应用从 (0,0) 的原点进行的转换,而 Chrome 则采用了 transform-origin 属性并正常工作。
我已经尝试了几乎所有我能找到的东西。有人有想法么?
