CSS实现⽂字头像（圆⾓头像⽂字内容）先上效果图。
关键css：
.avatar-container{
height: 1.5rem;
width: 1.5rem;
display: inline-block;
background: #aaaaaa;
text-align: center;
border-radius: 0.75rem;
}
.avatar-content{
margin-top: 0.25rem;
display: block;
}
其实本来想直接⽣成⼀张图⽚来着，后来发现js直接⽣成图⽚的效果不是很好，基本都是要⽤ canvas，效果、性能都是问题。后来发现⾃⼰真实傻，直接⽤css做⼀个出来不就⾏啦。
原理就是，⼀个div作为外壳，设置圆⾓，设置背景。把⽂字内容居中，OK了。
以下是例⼦的完整代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no"/>
