Fix `no-invalid-position-declaration` false positives for `@mixin` and `@scope` by ragini-pandey · Pull Request #9120 · stylelint/stylelint

ragini-pandey · 2026-03-01T04:14:04Z

Problem

The no-invalid-position-declaration rule incorrectly flags declarations inside nesting-supported at-rules (like @supports) when those at-rules are nested inside non-standard/preprocessor at-rules (like SCSS's @mixin, @if).

For example, the following valid SCSS was producing a false positive:

@mixin text-smart-justification($justify: true) {
  @if $justify {
    @supports (text-wrap: pretty) {
      text-wrap: pretty; /* ← false positive */
    }
  }
}

Root cause

When a declaration's parent is a nesting-supported at-rule (e.g., @supports), the rule walks up the tree using findNodeUpToRoot looking for a parent rule (selector) or an ignored at-rule. It walked past non-nesting-supported at-rules like @if and @mixin without recognizing them as valid contexts — even though declarations directly inside those at-rules are already allowed by the rule.

Fix

Updated the findNodeUpToRoot predicate to also treat ancestor non-nesting-supported at-rules as valid contexts. This makes the behavior consistent: if @mixin { color: red } is allowed, then @mixin { @supports (...) { color: red } } should also be allowed.

Testing

Added two accept test cases for declarations inside @supports/@media nested inside non-standard at-rules
Updated ignoreAtRules reject tests to reflect the corrected behavior
All 43 tests pass

Hi @ragini-pandey,

Thank you for working on this issue.

I am unsure how best to fix this.
Consider this Demo

/* standard and should all be valid: */
@scope (.foo) {
  color: red;
}

@mixin --foo() {
  color: red;
}

@mixin --foo() {
  @supports (color:red) {
    color: red;
  }
}

/* non-standard: */
@if (--foo) {
  color: red;
}

@if (--foo) {
  @supports (color:red) {
    color: red;
  }
}

@non-standard-style-rule {
  @if (--foo) {
    color: red;
  }
}

@non-standard-style-rule {
  @if (--foo) {
    @supports (color:red) {
      color: red;
    }
  }
}

/* invalid: */
color: red;

@keyframes {
  color: red; /* this should error, but doesn't? */
}

@keyframes {
  @if (--foo) {
    color: red; /* this should error, but doesn't? */
  }
}

@keyframes {
  @if (--foo) {
    @supports (color:red) {
      color: red;
    }
  }
}

Note how even some invalid positions aren't reported, like in @keyframes, you can ignore this, we can tackle that in a separate issue.

If we apply these examples to the proposed fix we get this Demo.
This now has some false negatives.

Maybe better if we instead consider @scope and @mixin to be equivalent to rules?
Both are specified as allowing declarations.

So instead of checking for something like this: (isAtRule(node) && !nestingSupportedAtKeywords.has(node.name.toLowerCase()))

We could instead change each instance of isRule(node) to (isRule(node) || (isAtRule(node) && declarationContainingAtRules.has(node.name.toLowerCase())))

Where declarationContainingAtRules is a set of mixin and scope.

(The declarationContainingAtRules maybe needs some bikeshedding)

I am unsure how best to fix this because the original issue was specifically about non-standard CSS, which we don't support. @mixin just so happens to also be a standard rule that is currently being worked on in browsers. So we can fix the original issue while staying within the bounds of standard CSS. However we should then update the issue and PR description to something like:

Fix no-invalid-position-declaration false positives for @mixin and @scope

But I don't think we can avoid false positives in this rule for non-standard at rules.
For non-standard CSS users should instead use the ignoreAtRules plugin option. (Demo)

What do you think?

@mixin

Address review feedback by: - Adding declarationContainingAtRules set with 'mixin' and 'scope' - Treating @mixin and @scope as equivalent to rules (both allow declarations) - Adding spec references for CSS Mixins and Cascade 6 - Updating tests to use standard @mixin/@scope instead of @unknown - Removing @scope reject test (now correctly allows declarations) This approach stays within standard CSS bounds and avoids false negatives. For non-standard at-rules, users should use ignoreAtRules option.

Thank you for the changes @ragini-pandey,
I've left a few more notes, please take a look when you have time.

 	reject: [
 		{
-			code: '@foo { @media all { color: red; } }',
-			message: messages.rejected,
-			line: 1,
-			column: 21,
-			endLine: 1,
-			endColumn: 32,
-		},
-		{
-			code: '@--bar { @media all { color: red; } }',
+			code: '@media all { color: red; }',
 			message: messages.rejected,
 			line: 1,
-			column: 23,
+			column: 14,
 			endLine: 1,
-			endColumn: 34,
+			endColumn: 25,
+			description: 'declaration directly in nesting-supported at-rule',
 		},


Should we keep the previous tests?

reject: [ { code: '@foo { @media all { color: red; } }', message: messages.rejected, line: 1, column: 21, endLine: 1, endColumn: 32, }, { code: '@--bar { @media all { color: red; } }', message: messages.rejected, line: 1, column: 23, endLine: 1, endColumn: 34, }, { code: '@media all { color: red; }', message: messages.rejected, line: 1, column: 14, endLine: 1, endColumn: 25, description: 'declaration directly in nesting-supported at-rule', }, ],

Yes, you are right! I have restored all three reject tests (@foo, @--bar, and @media all) in the ignoreAtRules section. They should indeed still reject since @foo does not match the configured patterns and @--bar does not match /^--bar-/ (missing trailing dash). Thanks for catching this!
