学习css3动画

 这个动画我们一起来看一下怎么实现

首先安排css部分

.circle_box{
  margin: 0 auto;
  background-image: linear-gradient(to right, rgba(29, 230, 179, 0.3), rgb(0, 247, 255));
  width: 500px;
  height: 300px;
  display: flex;
  justify-content: center;
  align-items: center;
}
.circleTrends{
  position: relative;
  width: 100px;
  height: 100px;
  display: flex;
  justify-content: center;
  align-items: center;
  
}
.circleTrends span{
  position: absolute;
  border:8px solid #fff;
  border-top: 8px solid transparent;
  border-radius: 99px;
}
.circleTrends span:nth-child(1){
  width: 80px;
  height: 80px;
  animation: span-one 2s infinite linear ;
}
.circleTrends span:nth-child(2){
  width: 40px;
  height: 40px;
  top:23px;
  left:23px; 
  animation: span-two 1s infinite linear ;
}
@keyframes span-one{
  0%{transform: rotate(360deg);opacity: 1.0;}
  50%{transform: rotate(180deg);opacity: 0.5;}
  100%{transform: rotate(0deg);opacity: 0;}
}
@keyframes spin-two{
    0%{transform: rotate(0deg); opacity: 0.5;}
    50%{transform: rotate(180deg); opacity: 1;}
    100%{transform: rotate(360deg);opacity: 0.5;}
}

html部分

<div class="circle_box">
      <div class="circleTrends">
      <span></span>
      <span></span>
      </div>
    </div>
