Sass Basics: Advanced Mixins

I'm stuck on the last quiz question. Here's my code.

index.html 
<!DOCTYPE html>
<html>
<head>
  <title>Sass Basics - Code Challenge</title>
  <link rel="stylesheet" type="text/css" href="page-style.css">
  <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
  <div class="box"></div>
  <div class="red"></div>
  <div class="orange"></div>
  <div class="yellow"></div>
  <div class="green"></div>
</body>
</html>
style.scss 
/* Write your SCSS code below. */
@mixin square ($size, $color: black) {
  height: $size;
  width: $size;
  border: 1px solid $color;
}
.box {
  @include square ($size: 10px, $color: red);
}
.box {
  @include square ($color: red, $size: 10px);
}
@mixin rainbow ($colors...) {
  @each $color in $colors {
    .color.#{$color} {
      background: $color;
    }
  }
}
@mixin rainbow ($color) {
  @each $color in red, orange, yellow, green {
   .color.#{$color} {
      background: $color;
    }
  }
}
.div {
  @include rainbow ($color: red);
}

Hi Kathryn,

You're not far off. Firstly, the question didn't specify creating divs with classes of the colors in the rainbow mixin, just general classes. Also, without wanting to give away the answer, remember the rainbow mixin accepts any number of arguments, ie (color1, color2, color3)

If my code is "@mixin rainbow ($colors...)" it give me a "Bummer!" message about the div. I eliminated my ".div" class from my code. I also tried "...($color 1, etc.)." I still get a "Bummer!" message about the div. I don't know what I'm missing in my code.

In your mixin, from the previous stage, you've already successfully set ($colors...) as your accepted arguments. So when you @include the mixin all you need to do is supply the colors the question asks for. If the question asked you to use the mixin to set red, white and blue classes, you'd do:

@include rainbow(red, white, blue);

Hope that helps. If it isn't clear to you why the above works, let me know.

If I don't change my "@mixin rainbow ($colors..)...@each $color in red..."and my "@include rainbow" includes the 4 colors, it still doesn't work.
