Full screen web app in iPhone 5 (save to home screen)
<!-- standard viewport tag to set the viewport to the device's width
, Android 2.3 devices need this so 100% width works properly and
doesn't allow children to blow up the viewport width-->
<meta name="viewport" id="vp" content="initial-scale=1.0,user-scalable=no,maximum-scale=1,width=device-width" />
<!-- width=device-width causes the iPhone 5 to letterbox the app, so
we want to exclude it for iPhone 5 to allow full screen apps -->
<meta name="viewport" id="vp" content="initial-scale=1.0,user-scalable=no,maximum-scale=1" media="(device-height: 568px)" />
<!-- provide the splash screens for iPhone 5 and previous -->
