How to remove WebStorm sass-lint error "Unknown pseudo selector 'ng-deep'"

Question

Angular 2+ with scss and ::ng-deep in WebStorm highlights this selector with text "Unknown pseudo selector 'ng-deep'"

I tried something like:

selector-pseudo-class-no-unknown: true
  ignorePseudoClasses: ng-deep

or

selector-pseudo-class-no-unknown: false

None of this works.

How to set exception in scss-lint.yml for this pseudo-selectors?

Answer 1

::ng-deep is pseudo element, not pseudo class. This is equivalent in my .stylelintrc

{
  "rules": {
    "selector-pseudo-element-no-unknown": [true, {
      "ignorePseudoElements": ["ng-deep"]
    }]
  }
}

Also you need to uncheck Settings -> Inspections -> CSS -> Invalid Elements -> Invalid CSS pseudo selector
