小编给大家分享一下怎么用CSS3和table标签实现一个圆形轨迹的动画，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
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> <h4>clickUrlKey:{{clickUrlKey}}</h4>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> @-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; } } .animation_div { -webkit-transform-origin:center center; -webkit-animation:round_animation 15s infinite alternate; 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; vertical-align: middle; line-height: 50px; } .color_blind { width: 50px; height: 50px; background-color: green; border-radius: 100px; text-align: center; vertical-align: middle; line-height: 50px; } .HR{ margin-left: -15px; width: 50px; height: 50px; background-color: blue; border-radius: 100px; text-align: center; vertical-align: middle; line-height: 50px; } .start_test { width: 60px; height: 60px; background-color: red; border-radius: 100px; text-align: center; vertical-align: middle; line-height: 50px; } .fat_content { margin-left: 15px; width: 50px; height: 50px; background-color: gray; border-radius: 100px; text-align: center; vertical-align: middle; line-height: 50px; } .WHR { width: 50px; height: 50px; background-color: purple; border-radius: 100px; text-align: center; vertical-align: middle; line-height: 50px; } .safe_period { width: 50px; height: 50px; background-color: yellow; border-radius: 100px; text-align: center; 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：
