+
+/// Builds directional properties by parsing CSS shorthand values. For example,
+/// a value of `10px null` will output top and bottom directional properties,
+/// but the `null` skips left and right from being output.
+///
+/// @argument {string} $property
+///   Base property.
+///
+/// @argument {string} $suffix
+///   Suffix to append. Use `null` to omit.
+///
+/// @argument {list} $values
+///   List of values to set for the property.
+///
+/// @example scss
+///   .element {
+///     @include _directional-property(border, width, null 5px);
+///   }
+///
+///   // CSS Output
+///   .element {
+///     border-right-width: 5px;
+///     border-left-width: 5px;
+///   }
+///
+/// @require {function} _compact-shorthand
