Named Mixin Parameters in SASS

Mixins can have named parameters. Let's look at this with the following example:

styles.scss@mixin active($color) {
  border: {
    color: $color;
    style: solid;
  }
}
p {
  @include active($color: orange);
}
div {
  @include active($color: green);
}

Compilation result:

styles.cssp {
  border-color: orange;
  border-style: solid;
}
div {
  border-color: green;
  border-style: solid;
}

In addition, you can pass default parameter values to mixins:

styles.scss@mixin active($color,  $width: 2px) {
  border: {
    color: $color;
    width: $width;
    style: dotted;
  }
}
p {
  @include active(yellow);
}
div {
  @include active(yellow, 4px);
}

After compilation we will see:

styles.cssp {
  border-color: yellow;
  border-width: 2px;
  border-style: dotted;
}
div {
  border-color: yellow;
  border-width: 4px;
  border-style: dotted;
}
