This is part of Tab's proposal at www-style, which can be found here: http://lists.w3.org/Archives/Public/www-style/2011Apr/0308.html Right now it doesn't cover the use case mentioned, because querying can be done only by valid CSS properties. Also only style rules are supported for now (it's not hard to add support for other types of rules, though). The overall implementation -- creating a document and then an element for each rule -- may seem a bit heavy-weight, so I'm glad to listen how (and if) we may improve it.

This will need extensive security review. CSS object lifetime safety in WebKit is largely dependent on how objects can be accessed - we recently had a number of security bugs caused by having CSSOM extensions.

I changed test case from patch into JSFiddle - https://jsfiddle.net/f7ex5azt/show I get error in Console across all browsers that it is queryRules is not function so I think no browser implemented it and this can be marked as "RESOLVED WONTFIX". Thanks!

Yeah, I don't think this experiment went anywhere. -> Won't fix.
