这个效果可以用作在网站的整体 Loading,也可以放在网站首屏当一个 banner 的背景也是非常棒的!

代码部分

html 部分代码:

  <span class="blue"></span>
</div>

css 部分代码:

.app{
  width:100%;
  height: 100vh;
  display: flex;

  height: 60px;
  margin: 40px;
  border-radius: 50%;
}
.red{
  animation: just1 2s ease-in-out infinite alternate;
}
.green{
  animation: just2 3s ease-in-out infinite alternate;
}
.blue{
  animation: just3 4s ease-in-out infinite alternate;
}
