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);
}
}
2、效果2
<div className='loading-con-o'>
<div className='load-item load-item-1'></div>
<div className='load-item load-item-2'></div>

<div className='load-item load-item-9'></div>
<div className='load-item load-item-10'></div>
<div className='load-item load-item-11'></div>
<div className='load-item load-item-12'></div>
<div className='text-loading'>加载中</div>
</div>
