纯CSS3实现antd旋转的四个小球加载中的动画特效

起因是接口超时了，导致项目页面进不去，一直转圈，我于是注意到了这个小东西：

还挺可爱哈，转起来眼睛都快晃瞎了。

于是我出于无聊旺盛的学习欲，照着antd的样式和速度改造了一下，做出来的……怎么说呢，好像也差不多吧：

嘎嘎真牛批啊我！

所以把代码贴一下，万一以后要做类似的，直接拿去用，舒服~

写完我又突发奇想想去看下antd怎么写的，总之万变不离其宗，，css3玩出花就对了，先记录下来吧：

这是html：

<div class="ant-spin ant-spin-lg ant-spin-spinning">
    <span class="ant-spin-dot ant-spin-dot-spin">
        <i class="ant-spin-dot-item"></i>
        <i class="ant-spin-dot-item"></i>
        <i class="ant-spin-dot-item"></i>
        <i class="ant-spin-dot-item"></i>
    </span>
</div>

这是css：

/* stylelint-disable at-rule-empty-line-before,at-rule-name-space-after,at-rule-no-unknown */
/* stylelint-disable no-duplicate-selectors */
/* stylelint-disable */
/* stylelint-disable declaration-bang-space-before,no-duplicate-selectors,string-no-newline */
