protected static function ScssNumber::getUnitOptions in SCSS Compiler 1.0.x

Get an associative array of unit options for the supplied element.

The supplied element's "#unit_options" property will determine the result of this method using the following algorithm:

1. If "#unit_options" is an array, it will be intersected with an internal list of allowed unit options. 2. Else, if "#unit_options" is a string, the desired unit will be extracted from an internal list of allowed unit options. 3. Else, if "#unit_options" is equivalent to TRUE, all allowed unit options will be produced. 4. Else, no unit options will be produced.


array $element: The element for which to get an associative array of unit options.

Return value

\Drupal\Core\StringTranslation\TranslatableMarkup[string] An associative array of unit option labels keyed by unit name.
