Use @each to Map Over Items in a List crome not working

Tell us what’s happening:
I dont why it is not working. Is the sass course buggy or am I doing something wrong. Please can some one help me.

Your code so far


<style type='text/sass'>
$colors: (color1: blue, color2: black, color3: red);
@each $key, $color in $colors {
  .#{$color}-text {color: $color; }
}
  

div {
    height: 200px;
    width: 200px;
    background-color: $colors;
  
.blue-bg {
  background-color: $color1;
}

.black-bg {
  background-color: $color2;
}

.red-bg {
  background-color: $color3;
}
</style>

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