tiny elements with high density screen

[jrm0695]

First, thank you for this awesome project; I'm integrating it with phonegap, but as I tried to run it on my phone (LG G4, very high density), all the elements were tiny looking (images and font). I saw some viewport meta tag, but none of them had fixed the issue. I tried to use media query, it worked on elements that have not been set in px but in em; and a lot of font-size statements are declared in px, in nd2 and in jqm.
The only solution to make everything looking the same correct size looks being to rummage through the css files looking for px declarations and putting them into em..

So .. are there any possible better alternatives with a couple of CSS line ?
