Tell us what’s happening:

Your code so far


<style type='text/sass'>
  @each $color in blue, black , red{
    .#{$color}-bg {background-color: $color;}
  }
  div {
    height: 200px;
    width: 200px;
  }
</style>

<div class="blue-bg"></div>
<div class="black-bg"></div>
<div class="red-bg"></div>

the test is very sensitive to spaces so rewrite it to look like this:

  @each $color in blue, black, red{
