While I recall that error recovery rules now allow what comes after a nested at-rule to be parsed, I'm not sure whether Chrome's behavior is conformant, or should be. 64600 1 sylvaing 2012-02-26 01:27:05 +0000 I suspect css-mediaqueries and/or css-conditionals would define this. 69746 2 sylvaing 2012-07-09 20:12:57 +0000 Whether @keyframes is valid inside another construct is really up to the module defining that construct. css3-animations should not define what is valid/invalid inside @media.
