Probleme in showing the view when I add a parameter in my Route

I want to pass a parameter to my controller from an URL,my code is:

• in web.php: Route::get('infoPatient/{id}','patientController@infoPatient');

• in my controller "patienController.php":

  public function infoPatient($id){
    $d=patientModel::find($id); 
    return view('/patient')->with('d',$d);
   }
  
  

  As a result, the view show data without any style.
