That was [initially pointed out by me](https://github.com/w3c/csswg-drafts/issues/6684#issuecomment-1064630704) and [later picked up](https://github.com/w3c/csswg-drafts/issues/6684#issuecomment-1071723157) by @nex3 as one possible solution with some restrictions. > Currently css `@if` conditionals with `media(...)` or `supports(...)` give parser errors. That's incorrect. E.g. `@if media(screen)` _is_ valid in Sass as pointed out by @nex3's comment linked to above. See also [one of my previous posts](https://github.com/w3c/csswg-drafts/issues/6684#issuecomment-1069762588). Having said that, there are no sites using the `media()` function in @rviscomi's data. That doesn't mean it's never used, though it can at least be seen as indicator that it is uncommon to use it. Though [according to its documentation](https://sass-lang.com/documentation/syntax/structure#other-expressions) Sass allows any core library or user-defined function as expression within [`@if`](https://sass-lang.com/documentation/at-rules/control/if). So while pure function calls without variables seem to be very uncommon according to the provided data, the CSS and Sass syntaxes for the conditions currently _do_ clash. This means that in order to let Sass' `@if` be a superset of CSS' `@if`, this possible clash needs to be avoided. And that again means to either change the syntax of CSS or Sass.
