CSS写的音频波纹效果

 HTML：

		<ul class="aubox">
			<li class="au1"></li>
			<li class="au2"></li>
			<li class="au3"></li>
			<li class="au4"></li>
			<li class="au5"></li>
			<li class="au6"></li>
			<li class="au7"></li>
		</ul>

CSS：

		.aubox{
			display: flex;
			align-items: flex-end;  //重要属性，让hight翻转过来，往上延伸
		}
		.auItem{
			width: 1px;
			margin-right: 5px;
			list-style: none;
			background: black;
			height:20px;
		}
		.au1{
			animation: audio .5s linear .1s infinite alternate;
		}
		.au2{
			animation: audio .5s linear .2s infinite alternate;
		}
		.au3{
			animation: audio .5s linear .5s infinite alternate;
		}
		.au4{

		}
		.au5{
			animation: audio .5s linear .2s infinite alternate;
		}
		.au6{
			animation: audio .5s linear .3s infinite alternate;
		}
		.au7{
			animation: audio .5s linear .1s infinite alternate;
		}
		@keyframes audio{
			from{height: 1px;}
			to{height: 20px;}
		}

直接复制上去就可以看效果了，本来想着让UI给做个GIF，UI一句不会GG。。
