Conditionals in Angular 2 using Sass

Looking to apply this style with Sass or CSS:

IF :host.form-control MATCHES .ng-valid[required] OR .ng-valid.required

THEN

:host ::ng-deep input.form-control = border-left: 5px solid #42A948;

Appreciate the help!

Answer №1

This question doesn't relate to 'Angular', but you can experiment with the following code snippet:

*:host {
    $self: &;

    &.ng-valid[required], &.ng-valid.required {
      #{$self}::ng-deep input.form-control {
        border-left: 5px solid #42A948;
      }
    }
}
