+表示新增
<head>
<meta charset="utf-8">
<title>weex-vue-demo</title>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">
<meta name="apple-touch-fullscreen" content="yes">
<meta name="format-detection" content="telephone=no, email=no">
<!-- <style>body > div { height: 100%; }</style> -->
<style>body::before { content: "1"; height: 1px; overflow: hidden; color: transparent; display: block; }</style>
