SCSS Map Function

Using #SCSS you can specify a a set of values in a map for easier access. Declare your map as a variable and reference it with the map-get SCSS function.

$colors: (
  "green": #008000,
  "red": #FF4136,
  "blue": #0074D9,
);

Reference that variable with the map-get function.

.bg-lg {
  background-color: map-get($colors, "green");
}
