What is the simplest way to make an HTML footer “sticky”?

Question

My aim is to have an HTML footer that sticks to the bottom (on a series of existing web pages). I am looking for a simple solution that doesn't require changing much code. Do you have experience with this issue or an idea? Thanks for your help!

Answer 1

Does setting css
position: sticky;
bottom: 0;
