On the "Зачем регистрироваться" page, the footer does not stick to the bottom of the viewport when there is little content, leaving an empty space below the main content.

Steps to Reproduce:¶

1. Open the page Зачем регистрироваться (qwertyshop.ua/zachem-registrirovatsya).
2. Scroll down and observe the footer's position.

Expected Result:¶

The footer should always be positioned at the bottom of the viewport when there is not enough content to push it down naturally.

Actual Result:¶

The footer floats above the bottom of the viewport, creating an empty gap.
