561580 - @media {} should be invalid (i.e., @media rules don't allow empty media lists)

Status: RESOLVED INVALID

(Core :: CSS Parsing and Computation, defect, P3)

Description

[David Baron :dbaron: (⌚️UTC-5, no longer working on Mozilla)]

In http://lists.w3.org/Archives/Public/www-style/2009Aug/0128.html the CSS working group resolved that @media rules should not allow empty media lists.  I wrote a patch for it immediately, but never got around to filing a bug.

(The minutes aren't all that clear, but the discussion was clear that the change was specific to @media and not a general media queries change.)

(I'll attach the patch once it passes try server; it requires at least one unit test adjustment and maybe more.)

Passes all unit tests on try on Linux and Mac.  Still waiting for Windows results, but no reason to think they'll be different.

The CSS working group decided at yesterday's telecon that it should be valid after all.  So this is now invalid.
