Today, I learned about the overall page zooming effect of QQ mailbox, the original implementation method is very simple, the code is as follows:

 
<!DOCTYPE html> 
<html> 
<head> 
<meta charset="utf-8" /> 
<meta name="viewport" content="width=device-width, initial-scale=1,maximum-scale=1, user-scalable=no"> 
<title> The test page </title> 
<style type="text/css"> 
div { 
width: 600px; 
text-align: center; 
font-size: 4em; 
color: #333; 
} 
</style> 
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.js"></script> 
<script type="text/javascript"> 
$(function() { 
var r = document.body.offsetWidth / window.screen.availWidth; 
$(document.body).css("-webkit-transform","scale(" + r + ")"); 
}); 
$(window).resize(function() { 
var r = document.body.offsetWidth / window.screen.availWidth; 
$(document.body).css("-webkit-transform","scale(" + r + ")"); 
}); 
</script> 
</head> 
<body> 
<div> Try changing the window size. What will you find? </div> 
</body> 
</html>
