Created 2011 May 7.
Played with an idea to add classes to the HTML element based on screen width by hacking away at Adapt.js. Classes like gte768 and lte768 etc. Check out the source - please excuse the lack of comments for my bits.
Test: Grey under 768, Blue over 768 with JS, Green over 768 without JS
It works, but is reliant on JavaScript. Without JavaScript it can fall back onto Media Queries by using a .js and .njs switch, however it does end up meaning duplication of CSS. So maybe not a goer really, but who knows, it may have a use.
May 9: Using a bit of server-side scripting could do the duplication donkey work.
May 9: Using sensible defaults like a desktop screen size layout could also work.
