A possible proposal from Henri is an attribute on <link> that opts an external style sheet out of synchronous CSSOM access, makes the sheet not load and not delay the load event if its media query cannot ever match in the UA even after zooming or invoking a print function, and makes the sheet load with low priority and not delay the load event if its media query does not match at the time the <link> element is inserted into the document but might match later (e.g. if it's a print style sheet, or depends on pixel density). 112322 1 ian 2014-09-26 21:36:16 +0000 This proposal or something close to it would handle this, I think: http://lists.w3.org/Archives/Public/public-whatwg-archive/2014Sep/0012.html 128749 2 annevk 2017-07-21 10:48:59 +0000 If this is still desired, please file a new issue at https://github.com/whatwg/html/issues/new.
