@media screen styles overridden by those without it

[jeremyschultz]

Respond.js writes its screen stylesheet before the media="all" stylesheet, so media queries with screen will be overridden by those that don't have a media type. This caused some unexpected behavior where a CSS rule with @media (min-width: 480px) that came before a @media screen and (min-width: 480px) ended up overriding the 2nd rule. It might make more sense to put the media="all" stylesheet first and media="screen" second.
