How to customize a shape when rendering in a view?

Question

Yii

Hello dear programmers!
In continuation, already a series of questions on yii2, I want to ask how to customize the form when rendering in the form. Those. using gii I have generated CRUD. And in the form of update.php I see this thing:

<?= $this->render('_form', [
        'model' => $model,
]) ?>

How to customize the form created in this form? Set CSS classes, and other options. If possible, then in an example, because I didn’t google Google =(
Please give an example.
