我正试图paths svg circles两个scale左右paths。我的目标是paths CSS位于中心位置，好像它们在搏动一样。我已经查看了stackoverflow上的每个答案，以找出如何实现这一目标。 The closest solution我发现没有炒锅。
这是我目前所拥有的jsfiddle。正如您所看到的，javascript正在缩小/朝向原点。如果无法通过Velocity.js实现此目标，是否可以使用 <div class="wrapper">

有一个简单的解决方案，即跨浏览器。
只要给你的每个阳光都有自己的绝对transform-origin。

我最终使用GSAP库来动画SVG。我选择这样做是因为没有解决方案可以在Chrome或Firefox上破坏动画。这是我测试过的可用于IE 11，Firefox和Chrome的代码。我使用了Jquery和TweenMax个库。
$(document).ready(function() {
var sun = $(".icon-sun");
var sunBeamEven = $(".icon-sun-beam:even");
var sunBeamOdd = $(".icon-sun-beam:odd");
function animateSun(){
TweenMax.to(sun, 12, {rotation:"+=360", svgOrigin:"50 50", smoothOrigin:true, repeat:-1, ease:Linear.easeNone});
TweenMax.to(sunBeamEven, 4, {scale:0.5, transformOrigin:"50% 50%", repeat:-1, yoyo:true, ease:Linear.easeNone});
TweenMax.to(sunBeamOdd, 4, {scale:0.5, transformOrigin:"50% 50%", repeat:-1, yoyo:true, ease:Linear.easeNone, delay:3});
}
animateSun();
