Note, that top and margin-top of footer are equal, except margin-top is negative

Answer 3

There are many ways to achieve that. Probably the best option is position: fixed. Other option is e.g. position: absolute; bottom: 0; But keep in mind you have to solve potential problems with overlapping the page content, position, responsive design etc. I would recommend using the position: fixed property together with flex or margin: auto; properties. Everything depends on the expected result ;-)
