用CSS3和table标签实现一个圆形轨迹的动画的示例代码

html：其实就是根据table标签把几个实心圆div进行等边六角形的排布，并放入一个div容器中，然后利用CSS3的循环旋转的动画效果对最外层的div容器进行自转实现，当然不要忘了把div容器的外边框设置圆形弧度的。

<div class="animation_div">        <table class="table_class"><tr>    <td></td>    <td>        <div class="BMI" ng-click="compriseClicked('BMI')" ng-class="{isSelected:clickUrlKey=='BMI'}"><strong>BMI</strong>        </div>    </td>    <td></td>    <td>        <div class="color_blind" ng-click="compriseClicked('color_blind')" ng-class="{isSelected:clickUrlKey=='color_blind'}"><strong>色盲色弱</strong>        </div>    </td>    <td></td></tr><tr>    <td>        <div class="space_div"></div>    </td></tr><tr>    <td>        <div class="HR" ng-click="compriseClicked('HR')" ng-class="{isSelected:clickUrlKey=='HR'}"><strong>心率</strong>        </div>    </td>    <td></td>    <td>        <a href="#/app/custom_made/counselor/{{clickUrlKey}}" style="text-decoration: none;color: black;"><div class="start_test">    <strong>开始测试</strong></div>        </a>    </td>    <td></td>    <td>        <div class="fat_content" ng-click="compriseClicked('fat_content')" ng-class="{isSelected:clickUrlKey=='fat_content'}"><strong>脂肪含量</strong>        </div>    </td></tr><tr>    <td>        <div class="space_div"></div>    </td></tr><tr>    <td></td>    <td>        <div class="WHR" ng-click="compriseClicked('WHR')" ng-class="{isSelected:clickUrlKey=='WHR'}"><strong>腰臀比</strong>        </div>    </td>    <td></td>    <td>        <div class="safe_period" ng-click="compriseClicked('safe_period')" ng-class="{isSelected:clickUrlKey=='safe_period'}"><strong>安全期</strong>        </div>    </td>    <td></td></tr>        </table>    </div>        <h3>clickUrlKey:{{clickUrlKey}}</h3>

css：因为在圆形的轨迹中有6个实心圆，分别设置了不同的类以方便自定义，所以当中实心圆的样式设置有重复的地方，还可以进行优化，在这就先不处理了

<style>      /*定义动画*/@-webkit-keyframes round_animation {          0%{  -webkit-transform:rotate(0deg);  width:260px;  height:260px;          }          100%{  -webkit-transform:rotate(360deg);  width:260px;  height:260px;  left:0px;  top:0px;          }      }/*定义外框的样式*/      /*调用动画并设置动画的参数*/.animation_div {          -webkit-transform-origin:center center;           /*定义旋转中心点*/          -webkit-animation:round_animation 15s infinite alternate;     /*infinite alternate表示循环播放动画*/        margin: 60px auto;          width:260px;          height:260px;          border: 1px solid black;          border-radius: 130px;          left:0px;          top:0px;      }.animation_div strong {          font-size: 12px;      }.BMI {          width: 50px;          height: 50px;          background-color: orange;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.color_blind {          width: 50px;          height: 50px;          background-color: green;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.HR{          margin-left: -15px;          width: 50px;          height: 50px;          background-color: blue;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.start_test {          width: 60px;          height: 60px;          background-color: red;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.fat_content {          margin-left: 15px;          width: 50px;          height: 50px;          background-color: gray;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.WHR {          width: 50px;          height: 50px;          background-color: purple;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.safe_period {          width: 50px;          height: 50px;          background-color: yellow;          border-radius: 100px;          text-align: center;        /*文字垂直居中*/          vertical-align: middle;          line-height: 50px;      }.space_div {          width: 50px;          height: 50px;          background-color: clear;          border-radius: 100px;      }.rightmenu_btn {          height: 60px;          float: none;      }.rightmenu_btn button {          margin-top: 50px;          width: 20px;          height: 60px;          border: 1px solid rgb(221, 221, 221);          border-right: 0px;          float: right;      }.isSelected {          border: 1px solid red;      }  </style>

JS：这里的代码可以不实现，因为这跟动画的效果无关，是一个点击的响应事件

angular.module('starter.controllers', [])    .controller('healthCtrl', function($scope, $location) {        $scope.clickUrlKey = "BMI";        $scope.compriseClicked = function(clickUrlKey) {$scope.clickUrlKey = clickUrlKey;        };    })

效果图如下：
