为什么在vue工程中引入iconfont有时候不生效呢？
请依次使用以下方法
1. 在index.html中引入在线资源
<!DOCTYPE html>
<html lang="en" style='height: 100%;'>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">
<!-- 引入下面这个cdn资源 -->
<link rel="icon" href="//at.alicdn.com/t/font_918300_q5yxfof3wjo.css">
<title>vue-shop-front</title>
</head>
<body style='height: 100%;'>
<noscript>
<strong>We're sorry but vue-shop-front doesn't work properly without JavaScript enabled. Please enable it to
continue.</strong>
</noscript>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
2. 在mainjs中使用Vue.use()引入
Vue.use('//at.alicdn.com/t/font_918300_q5yxfof3wjo.css')
3. 在App.vue中import引入（前提是你得使用了预处理器）
<style lang="scss" scoped>
@import url("//at.alicdn.com/t/font_918300_q5yxfof3wjo.css");
#wrap-box {
height: 100%;
// height: 1000px;
}
</style>
