用纯CSS实现加载的一些动态效果,可以把加载效果中的元素分成很多个小部分,每个部分都有动画,每个部分的动画再设置相应的延迟效果,这样,看起来就是连贯的加载动画效果。代码如下:

1、效果1

<div className=\'loading-con\'>
      <div className=\'load-dian dian1\'></div>
       <div className=\'load-dian dian2\'></div>
       <div className=\'load-dian dian3\'></div>
       <div className=\'load-dian dian4\'></div>
       <div className=\'load-dian dian5\'></div>
       <div className=\'text-loading\'>加载中</div>
 </div>
.loading-con{
  position: absolute;
  top: 50%;
  width: 100px;
  height: 100px;
  left: 50%;
  transform: translate(-50%,-50%);
  background: rgba(0,0,0,0.65);
  border-radius: 8px;
}
.load-dian{
  position: absolute;
  width: 8px;
  height: 8px;
  border-radius: 5px;
  background: #fff;
  top: 40%;
  -webkit-animation: Loading-delay 1.2s infinite ease-in-out both;
  animation: Loading-delay 1.2s infinite ease-in-out both;
}
.dian1{
  left: 15%;
  -webkit-animation-delay: -1.1s;
  animation-delay: -1.1s;
}
.dian2{
  left: 30%;
  -webkit-animation-delay: -1s;
  animation-delay: -1s;
}
.dian3{
  left: 45%;
  -webkit-animation-delay: -0.9s;
  animation-delay: -0.9s;
}
.dian4{
  left: 60%;
  -webkit-animation-delay: -0.8s;
  animation-delay: -0.8s;
}
.dian5{
  left: 75%;
  -webkit-animation-delay: -0.7s;
  animation-delay: -0.7s;
}
@-webkit-keyframes Loading-delay {
  0%, 100% {
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  40% {
    -webkit-transform: scale(1);
    transform: scale(1);
  }
}
