使用bootcdn字体图标库。
选带有min这个，引入到html文件中
我一开始复制的是这一个，结果不能显示图标
<link href="https://cdn.bootcdn.net/ajax/libs/font-awesome/6.4.0/css/fontawesome.min.css" rel="stylesheet">
后来查看图标库的使用说明发现是需要引入这个带有all.min.css的，就可以正常使用的
<link href="https://cdn.bootcdn.net/ajax/libs/font-awesome/6.4.0/css/all.min.css" rel="stylesheet">
图标库：图标库 - FontAwesome 字体图标中文Icon
搜索关键字，点击想要的图标复制代码即可。
最后的实现效果及代码：
代码：
show12.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>侧边导航栏2</title>
<!-- 引入字体图标库 -->
<link href="https://cdn.bootcdn.net/ajax/libs/font-awesome/6.4.0/css/all.min.css" rel="stylesheet">
<link rel="stylesheet" href="show12.css">
