How to translate from less to sass?

Question

Layout

I have this code in less:

.fonts(@size, @lineheight, @bold:normal){
  font-size: @size;
  line-height: @lineheight;
  font-weight: @bold;
}
.fonts(11px, 50px, bold);

Can you tell me how to convert it to sass??
so that the same thing could be used in sass.
This is sass, do not confuse it with scss

Answer 1

@mixin fonts($size, $lineheight, $bold:normal){
  font-size: $size;
  line-height: $lineheight;
  font-weight: $bold;
}

.fonts { 
  @include fonts(11px, 50px, bold);
}
