A userscript to assist you in your responsive devs
Our latest responsive site is partially responsive from the server side rendering.
This script automatically refresh the page with the proper device format, as you resize the page.
As chrome is slightly painful (they probably got good concerns), you can't install a userscript directly... see http://userscripts.org/about/installing
The trick is too install the Tampermonkey extension, and then load the script: https://github.com/jobwat/responsive-refresh-userscript/raw/master/responsive-refresh.user.js
Innovate in a dynamic triggering mechanism to enable this userscript on some conditions only (url is not enough in dev mode..)
I've started the same project as a Chrome Extension first but couldn't get the viewport dimensions, only the window ones.
