I've just run a few batch tests on this version over some staging web sites.
1) I didn't see that @import issue. Thanks.
2) I didn't see those stray hard to close dialogs, not meaningful without more starts.
3) I got a few
(These come from content which has been updated by an online CMS system.) It struck me that these would be a lot clearer if the whitespace was shown as visible characters. (Paragraph sign, dots for spaces, guillemets for tabs etc.)The text content of the "a" element begins and ends with whitespace. This may not be wanted.
4) For the colour difference message I get something like
My first thought was, what are these priority levels? I think incorporating the words, must, should and may would make the meaning clearer to all. It is worth considering a switch on these messages, show none, show musts, show musts and shoulds... They have booleanised the tests, but clearly a more thorough implementation would give better "recommendation resolution" though I wouldn't really expect to see that in the spec...The color difference between the foreground color and background color is 408. This is below the recommended value of 500. [P3, 2.2] (NOTE: Sufficient contrast is Priority 2 for images, Priority 3 for text; assuming text here)
5) The colour difference messages continue to flag CSS sheets that are intended to be that way.
