1. Responsive navigation menu

When the viewport is larger than 640px, the navigation bar will be displayed outside. When the viewport is smaller than 768px Sometimes, the navigation menu needs to be hidden!
The code is as follows:

<!doctype html>
<html>
<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width">
    <title>响应式</title>

    <link rel="stylesheet" type="text/css" href="demo1.css"/>
    <link href="https://cdn.bootcss.com/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet">

</head>
<body>

    <p class="nav">
    <p class="pic"></p>
        <p class="btn">
            <i id="btn" class="fa fa-bars"></i>
        </p>
        <ul id="menu" class="clearfix">
            <li><a href="#">首页</a></li>
            <li><a href="#">产品</a></li>
            <li><a href="#">购买</a></li>
            <li><a href="#">服务</a></li>
            <li><a href="#">联系</a></li>
        
        </ul>
    
    </p>
    
    <script type="text/javascript">
        var btn=document.getElementById("btn");
        var menu=document.getElementById("menu");
        
        btn.onclick=function(){
            if(menu.style.display=="block"){
                menu.style.display="none";
            }
            else{
                menu.style.display="block";
            }
            
            window.onresize=function(){
                var vw=document.documentElement.clientWidth;
                if(vw>640){
                menu.style.display="block"};
            }
        }
