今天也是用css动画来完成一个加载转圈效果哦~感觉比上次加载旋转的效果棒多了，哈哈，body颜色也是喜欢的颜色~不多说，下面上css代码，就是用css动画来完成的~
<style style="text/css">
body{
margin: 0;
background:rgb(13,206,203)
}
div{
width: 20px;
height: 20px;
border-radius: 50%;
background-color:transparent;
margin: 200px auto;
animation-name: turn;
animation-duration: 2s;
animation-iteration-count: infinite;
animation-timing-function: linear;
}
@keyframes turn{
