SASS Maps

maps.scss

// The idea here is that you can define all your variables into a single $properties value and refer to them 
// throughout the SASS project files.
// Potential usecase: Defining common values and Foundation 5 overrides

$properties: (
  background: red,
  color: blue,
  font-size: 1em,
  font-family: (Helvetica, arial, sans-serif)
);

.foo {
  color: map-get($properties, color);
}
