Adding CSS styles to our module

We decided to use the actionFrontControllerSetMedia hook execution to manage the insertion of our CSS style sheet into all the website pages. As $params is an empty array, in that case, there is no way to act on any variable.

The solution is to use $this->context, the instantiation of the Context singleton. It contains the controller variable, an instance of the current controller object, and a child class of FrontController. Then, we can use registerStylesheet($id, $relativePath, $params = []), available in all instances of FrontController. Let’s see how to do it for real:

public function hookActionFrontControllerSetMedia($params)
{
     $this->context->controller->registerStylesheet(
        'whreinsurance-style',
        $this->_path.'views/css/whreinsurance.css',
      ...
