Respond.js is a lightweight polyfill for min/max-width CSS3 Media Queries for IE 6-8, however be careful with your comments.
I have been working with Responsive Web Design for some time now, which works great with all modern browsers, but IE is a problem (especially IE 6-8). This is where Respond.js comes in.
While debugging a seemingly baffling problem, I found this issue.

This is more a "Gottya" than a bug and I have not checked the code yet, but maybe this will save someone else some head scratching.
Issue was that Respond would stop parsing a style sheet before the end. After a bit of trial and error, problem was due to a comment in the form
/* blah blah blah } blah */
Removing the '}' fixed the problem.
Solution: Don't put '}' characters in comments.
