Any plans to do a full release?

This is a stub sandbox at the moment :(

For now I'd recommend Modernizr which can bundle respond.js

The sandbox now contains the basic functionality you need to get up and running. I'm going to implement Libraries support at the very least before tagging a release.

I could not get this to module to work on IE. Eventually I realized/read that respond.js does not work with stylesheets pulled into a page using @import, which is how drupal pulls in stylesheet via the .info file. Instead, put the stylesheet that will use the media queries directly into your html.tpl.php file just after print $styles;

Hope that helps someone.

@Michael Ware - That's correct. This script only works with <link> and will not work with @import. However, Drupal 7 uses <link> tags for stylesheets when you enable CSS aggregation, so it starts working at that point. It's a good idea to enable this setting on all production websites anyway.

Navigate to /admin/config/development/performance. Enable Aggregate and compress CSS files.

I have added a note to the project page, and will open a separate issue for some sort of administrative warning that reminds users that respond.js will not work until they enable CSS aggregation.

Issue can be tracked here: #1350130: Issue an administrative warning when CSS aggregation is disabled

Release has been tagged, should be available on d.o momentarily!
