Answer 1

Correct me if I have misunderstood your question, you're trying to have a sticky footer that will fill your container. You can simply do it by adding these two lines footer selector in your CSS file:

footer {
    position: 'sticky';
    height: '100vh';
}

Answer 2

You can use this code - footer fixed and sticky working and footer so footer all link is not clickable.

                        <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.</p>
