If you don't specify a viewport for content served from a .mobi domain the rendering engine assumes a certain viewport other than for content served from a .com domain. If you define your own viewport it will be ignored. See this article: http://www.davidroessli.com/logs/2010/04/safari_ignores_viewport_mobi_domains/ e.g.: we deliver the exact same content from http://www.caruso.mobi and from http://www.carusocarsharing.com On the .mobi domain you can't zoom out to see the entire page. On the .com domain you can! You can try it by yourself on your iPhone here: Everything OK: http://www.carusocarsharing.com/static/css/test.html clientWidth: 980 clientHeight: 1091 window.innerWidth: 980 window.innerHeight: 1091 screen.width: 320 screen.height: 480 **************************************** Doesn't work as expected: http://www.caruso.mobi/static/css/test.html clientWidth: 320 clientHeight: 356 window.innerWidth: 320 window.innerHeight: 356 screen.width: 320 screen.height: 480 788120 1 pp 2012-12-11 00:29:02 -0800 In the meantime we redirect from http://www.caruso.mobi/static/css/test.html to http://www.carusocarsharing.com/static/css/test.html Not even then does the viewport work as expected! But if you directly go to http://www.carusocarsharing.com/static/css/test.html it works as expected (you can zoom in and out properly with the magnifying gesture on the iPhone / iPad) 857673 2 ap 2013-03-18 16:06:26 -0700 See also: bug 108982. 864954 3 ap 2013-03-27 16:05:34 -0700 *** Bug 112633 has been marked as a duplicate of this bug. *** 922267 4 psolanki 2013-08-28 17:08:45 -0700 <rdar://problem/12369131>
