Make HTML page scaling fit for mobile client dimensions

Don't say a lot, just look at the code.

<script type= "Text/javascript" >var w = screen.width;var rate = "0.55", switch (w) {Case 320:case 6                    40:rate = "0.5";                Break                    Case 365:case 720:case 375:case 750:rate = "0.585";                Break                    Case 414:case 1242:case 1080:rate = "0.64";                Break                    Default:rate = "0.55"; break;} document.write ("<meta name= ' viewport ' content= ' width=device-width,initial-scale=" +rate+ ", minimum-scale=0.2, maximum-scale=1, User-scalable=no ' > ");</script><meta charset= "UTF-8" ><title>DEMO</title><!--atwind | Chaosstudio http://cszi.com--><link rel= "stylesheet" href= "Css/normalize.css" >
