Vary simple way to feed different CSS based on characteristic users' device. Make us to re-think about "device". Maybe easy to retrofix existing design.

(ie. iPhone4), screen resolution is 640x960 that specification say so. So, can we use @media ( max-width: 640px ) to do our job? NO. You should use @media ( max-width: 320px ) cause the device-pixel-ratio is 2.
that was 100px by 100px, you'd provide an image that was 200px by 200px, but specify in CSS or as an attribute in HTML that it is 100px by 100px. The reason this works is that a pixel on the screen is not the same as a CSS pixel. This is a good thing, because otherwise as I say, things would be tiny. --Rich Bradshaw ” Pixel density, retina display and font-size in CSS

failed. Retrofit existing design is too difficult. Original design is NOT content first. Visual design cannot reuse in the narrow styles. Alomst overwriting all the style we have. Vary hard to fine tune in the mobile device. We do REALLY not want to test Android devices.
which the device really have and IT IS READ-ONLY. In the other word, it called "visual viewport". actual viewport After initial viewport, this is the rules you setting in the viewport, in the other word, it called "layout viewport".

media query or Javascript. DO NOT USE strange setting with @viewport, if you don'y know why you do. Use the @media carefully, do the @media style once, not overwriting at all. Think about your content again. DO NOT fight with your visual designer.
