html – 使用CSS在圆圈周围旋转对象？

我试图围绕一个圆圈旋转三个物体.到目前为止,我已经能够让一个物体围绕圆圈旋转.如果不弄乱代码,我无法获得多个.任何人都可以建议最好的方法来实现这一目标吗？这是代码和小提琴的一部分.谢谢！

这是Demo

.outCircle {
  width: 200px;
  height: 200px;
  background-color: lightblue;
  left: 270px;
  position: absolute;
  top: 50px;
  -moz-border-radius: 100px;
  -webkit-border-radius: 100px;
  border-radius: 100px;
}
.rotate {
  width: 100%;
  height: 100%;
  -webkit-animation: circle 10s infinite linear;
}
.counterrotate {
  width: 50px;
  height: 50px;
  -webkit-animation: ccircle 10s infinite linear;
}
.inner {
  width: 100px;
  height: 100px;
  background: red;
  -moz-border-radius: 50px;
  -webkit-border-radius: 50px;
  border-radius: 100px;
  position: absolute;
  left: 0px;
  top: 0px;
  background-color: red;
  display: block;
}
@-webkit-keyframes circle {
  from {
    -webkit-transform: rotateZ(0deg)
  }
  to {
    -webkit-transform: rotateZ(360deg)
  }
}
@-webkit-keyframes ccircle {
  from {
    -webkit-transform: rotateZ(360deg)
  }
  to {
    -webkit-transform: rotateZ(0deg)
  }
}

<div class="outCircle">
  <div class="rotate">
    <div class="counterrotate">
      <div class="inner">hello
      </div>
    </div>
  </div>
</div>

解决方法

Jquery解决方案适用于任何数量的外部项目.

Jquery从ThiefMaster♦无耻地偷走了他们在Q & A的回答

var radius = 100; // adjust to move out items in and out 
var fields = $('.item'),container = $('#container'),width = container.width(),height = container.height();
var angle = 0,step = (2 * Math.PI) / fields.length;
fields.each(function() {
  var x = Math.round(width / 2 + radius * Math.cos(angle) - $(this).width() / 2);
  var y = Math.round(height / 2 + radius * Math.sin(angle) - $(this).height() / 2);
  if (window.console) {
    console.log($(this).text(),x,y);
  }
  $(this).css({
    left: x + 'px',top: y + 'px'
  });
  angle += step;
});

body {
  padding: 2em;
}
#container {
  width: 200px;
  height: 200px;
  margin: 10px auto;
  border: 1px solid #000;
  position: relative;
  border-radius: 50%;
  animation: spin 10s linear infinite;
}
.item {
  width: 30px;
  height: 30px;
  line-height: 30px;
  text-align: center;
  border-radius: 50%;
  position: absolute;
  background: #f00;
  animation: spin 10s linear infinite reverse;
}
@keyframes spin {
  100% {
    transform: rotate(1turn);
  }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
  <div class="item">1</div>
  <div class="item">2</div>
  <div class="item">3</div>
  <div class="item">4</div>
  <div class="item">5</div>
  <div class="item">6</div>
</div>
