纯css实现loading加载中（多种展现形式）
前言
现如今网页越来越趋近于动画，相信大家平时浏览网页或多或少都能看到一些动画效果，今天我们来做一个有意思的动画效果，纯 css 实现 loading 加载中（多种展现形式），下面一起看看吧。
1. 常规 loading
实现效果
代码如下
<template><div class="parentBox"><div class="loadBox"><div class="loaderContantBox"></div></div></div>
</template>
<style lang="less" scoped>
.parentBox {height: 100%;background: rgb(31, 31, 31);padding: 100px;.loadBox .loaderContantBox {color: white;font-size: 40px;overflow: hidden;width: 40px;height: 40px;border-radius: 50%;transform: translateZ(0);/* animation：规定完成动画所花费的时间，该属性必须规定，否则动画时长为0，无法播放 */animation: loadBox 1.7s infinite ease, round 1.7s infinite ease;}@keyframes loadBox {0% {box-shadow: 0 -0.83em 0 -0.4em, 0 -0.83em 0 -0.42em, 0 -0.83em 0 -0.44em,0 -0.83em 0 -0.46em, 0 -0.83em 0 -0.477em;}5%,95% {box-shadow: 0 -0.83em 0 -0.4em, 0 -0.83em 0 -0.42em, 0 -0.83em 0 -0.44em,0 -0.83em 0 -0.46em, 0 -0.83em 0 -0.477em;}10%,59% {box-shadow: 0 -0.83em 0 -0.4em, -0.087em -0.825em 0 -0.42em,-0.173em -0.812em 0 -0.44em, -0.256em -0.789em 0 -0.46em,-0.297em -0.775em 0 -0.477em;}20% {box-shadow: 0 -0.83em 0 -0.4em, -0.338em -0.758em 0 -0.42em,-0.555em -0.617em 0 -0.44em, -0.671em -0.488em 0 -0.46em,-0.749em -0.34em 0 -0.477em;}38% {box-shadow: 0 -0.83em 0 -0.4em, -0.377em -0.74em 0 -0.42em,-0.645em -0.522em 0 -0.44em, -0.775em -0.297em 0 -0.46em,-0.82em -0.09em 0 -0.477em;}100% {box-shadow: 0 -0.83em 0 -0.4em, 0 -0.83em 0 -0.42em, 0 -0.83em 0 -0.44em,0 -0.83em 0 -0.46em, 0 -0.83em 0 -0.477em;}}@keyframes round {0% {transform: rotate(0deg); /* 开始旋转 div 元素 */}100% {transform: rotate(360deg); /* 结束旋转 div 元素 */}}
