I edited this gist (now here: https://gist.github.com/1668965) to improve the syntax and compatibility to common and already used style.
This provides the possibility to use real media-queries as syntax and detect also features like monochrome display (Kindle etc.).
We also could use alt and title text there. Thing is, browser-vendors need to implement it that way so the current alt text and title text is replacing the original one. But I think this isn’t a problem.
And stay updated about the W3C draft proposal here: http://novolo.de/blog/2012/01/19/what-happened-to-responsive-assets/
It will be soon on a W3C mailing list, I hope to get docs finished by end of the week.
Wow... thanks for the fork. I had no idea this was going to go anywhere. Please keep me informed about the status of the W3C proposal.
Thanks a mil,
It's a great proposal and along with mine we now have two valid options which I propose to the W3C soon. So I hope to get this real as it's a problem we should face as soon as possible.
