Hi, The "Unexpected end of style sheet" rule of CSS 2.1 says " User agents must close all open constructs (for example: blocks, parentheses, brackets, rules, strings, and comments) at the end of the style sheet." Does this apply to rules that are (in Syntax 3 terms) in their "prelude"? For example: 1. @import "foo.css"/* No semicolon */<EOF> 2. @media print/* No block */<EOF> 3. h1, h2/* No block */<EOF> Only 1. has an effect on the cascade, but all three examples are testable in CSS OM. In the Syntax 3 ED as current written, EOF in the middle of an at-rule’s prelude, it implies a semicolon: 1. is assumed to be @import "foo.css"; and is valid 2. is assumed to be @media print; which is not a valid @media rule In a qualified rule prelude (as in 3.) EOF is an error and the rule is dropped. In other words, EOF in the middle of a selector does *not* create a style rule in the OM. Mozilla issue: https://bugzilla.mozilla.org/show_bug.cgi?id=446226 I think that this Syntax 3 behavior makes the most sense, and would like to check WG consensus. Cheers, -- Simon Sapin
