active form. How to increase the length of the input field?

Question

Yii

Just came to Yii. I confess, but please explain how I can increase the length of small inputs. On pure bootstrap, this is done only by changing the number, but here I can’t understand.
Taking this opportunity, I want to ask a question: "How can I add attributes to these fields, for example: "placeholder".

Answer 1

<?= $form->field($model, 'field_name')->textInput(['placeholder' => 'Placeholder text']) ?>
Length - css

Answer 2

Thank you! Just found a similar solution.

<?= $form->field($model, 'name', [
    'inputOptions' => ['placeholder' => 'Ваше имя']
]); ?>

I will work now with styles.
