The site displays fine (vertically) in Android and most other phones, EXCEPT Iphones 4 and 5.
Iphone squeezes the page into the screen rather than resize responsively. I have a responsive layout with media queries in
various break points.
I have been testing in Google’s Developer Emulator and see that Iphone seems think the width is 980px which is not
set like that anywhere in the stylesheet.
I’ve just done a quick test using the mac simulator and I can see that the site is not applying the media queries properly and is just scaled to fit as though you had omitted the viewport meta tag.
The problem seems to be connected with the simpleviewer script you have in place and if I remove references to that script then the page reformats properly on the iphone(simulator) . So the first thing to try is just to remove that script and test to see if this really is the cause. If so then you will need to contact the support section of the simpleviewer site as this a paid for product and should be fully supported.
Ralph, the site is redirected to mobile so you can’t easily test on a desktop. You can get a chrome extension that lets you spoof the header and see the mobile code.
