Who Queries the Feature Queries? @​supports not ( @​supports selector() ) { … } It's not a good idea, but it is AN idea - so that's something, right? Conditionals all the way down.

We'd probably want to add an at-rule() function alongside the selector() function defined in drafts.csswg.org/css-conditi… -- but I'm not sure "at-rule()" is really a good name... and what *is* a good name. The hard part of adding this feature may be figuring out what to call it.

Yep, my first draft of that tweet used "feature-query()" and I thought it looked too real to be funny. You would also have to supply both the rule type (media/supports) and the condition type (selector())… @​supports conditional(supports selector()) ???
