php - Symfony adding style to each input field

I have a function, in Symfony2, that creates a form. Then I load it using twig and everything works fine.

The problem is that I would like to add style to each label and each input, separately, and I can only add style to the whole form.

private function createEditForm(Client $entity)
{
    $form = $this->createForm(new ClientType(), $entity, array(
        'action' => $this->generateUrl('client_update', array('id' => $entity->getId())),
        'method' => 'PUT',

    ));

    $form->add('submit', 'submit', array('label' => 'Update'));

    return $form;
}
Copy code

Could I do it the way I'm doing it or do I have to rebuild the function so it doesn't create the form dynamically from an array?

Thank you.
