In Sass, how to reference two parent classes with ampersand to compound with an element?

Question

Using the method found here, it works, but not for two parent classes.

For instance:

.one, .two {
  @at-root a#{&} {
    color: blue;
  }
}
         


        

Answer 1

Or you simply switch to stylus:

.one,
 .two {
   a& {
   color: blue;
 }
}
