#is_superselector($super, $sub) ⇒ Sass::Script::Value::Bool

is-superselector(".foo", ".foo.bar") => true
is-superselector(".foo.bar", ".foo") => false
is-superselector(".bar", ".foo .bar") => true
is-superselector(".foo .bar", ".bar") => false

Returns Whether $selector1 is a superselector of $selector2.

Parameters:

• $super (Sass::Script::Value::String, Sass::Script::Value::List) —

  The potential superselector. This can be either a string, a list of strings, or a list of lists of strings as returned by &.

• $sub (Sass::Script::Value::String, Sass::Script::Value::List) —

  The potential subselector. This can be either a string, a list of strings, or a list of lists of strings as returned by &.

Returns:

• (Sass::Script::Value::Bool) —

  Whether $selector1 is a superselector of $selector2.
