怎样制作出仿小程序动画三个圆点？

Question

如下图所示，自己使用css写了一下但是不太流畅看着有点不太相同，需要用到js吗？有小例子的话希望可以参考一下，就是我看有的小程序进入页面就会出现这个加载，是自己手写的吗？

Answer 1

小程序的下拉刷新会出现三个原点，onPullDownRefresh()

Answer 2

通过CSS动画就可以实现

.stage {
    display: flex;
    justify-content: center;
    align-items: center;
    padding: 2rem 0;
    margin: 0 -5%;
    overflow: hidden;
}

.dot-flashing {
    position: relative;
    width: 10px;
    height: 10px;
    border-radius: 5px;
    background-color: #9880ff;
    color: #9880ff;
    animation: dotFlashing 1s infinite linear alternate;
    animation-delay: .5s;
}

.dot-flashing::before {
    left: -15px;
    animation: dotFlashing 1s infinite alternate;
    animation-delay: 0s;
}

.dot-flashing::after {
    left: 15px;
    animation: dotFlashing 1s infinite alternate;
    animation-delay: 1s;
}

.dot-flashing::before,
.dot-flashing::after {
    content: '';
    display: inline-block;
    position: absolute;
    top: 0;
    width: 10px;
    height: 10px;
    border-radius: 5px;
    background-color: #9880ff;
    color: #9880ff;
}

@keyframes dotFlashing {
    0% {
        background-color: #9880ff
    }

    100% {
        background-color: #ebe6ff
    }
}

<div class="stage">
    <div class="dot-flashing"></div>
</div>
