SCSS Reverse direction

There may be a point in your CSS coding that you want to know the opposite of a direction (e.g. up, down). This function allows you to pass it a direction and get the opposite back!‚Äč

Fairly basic principle. If it can't find the opposite it just returns what it was passed. Verbose function name so it don't conflict with anything else.

@function reverseDirection($direction) {
$output: $direction;
@if $direction == right {
$output: left;
} @else if $direction == left {
$output: right;
} @else if $direction == up {
$output: down;
} @else if $direction == down {
$output: up;
} @else {
@debug 'Could not reverse #{$direction}';
@return $output;
