Sass allows you to pass in multiple arguments in a list or a map format.

For example, take the multiple properties needed to create the college-ruled stripes in the back of our notecard.

@mixin stripes($direction, $width-percent, $stripe-color, $stripe-background: #FFF) {
  background: repeating-linear-gradient(
    $direction,
    $stripe-background,
    $stripe-background ($width-percent - 1),
    $stripe-color 1%,
    $stripe-background $width-percent
  );
}

In this scenario, it makes sense to create a map with these properties in case we ever want to update or reference them.

$college-ruled-style: ( 
    direction: to bottom,
    width-percent: 15%,
    stripe-color: blue,
    stripe-background: white
);

When we include our mixin, we can then pass in these arguments in a map with the following ... notation:

.definition {
      width: 100%;
      height: 100%;
      @include stripes($college-ruled-style...);
 }

Note: Remember to always prioritize readability over writing less code. This approach is only useful if you find it adds clarity to your codebase.
