view story

http://stackoverflow.com – I did design an android app so the application link the visitor to my website's mobile version "jQuery Mobile". everything is good when I open the mobile version on default android browser. the problem is when I open it inside WebView, The retina @2x doesn't work on WebView. Here is my codes : META : <meta content="width=device-width, minimum-scale=1, maximum-scale=1" name="viewport"> CSS : .replace-2x { font-size: 1px; } JAVASCRIPT : function highdpi_init() { if(jQuery('.replace-2x').css('font-size') == "1px") { var els = jQuery("img.replace-2x").get(); (HowTos)
