Place the footer AND the copyright blocks at the bottom of the page responsive
If you are indeed looking to create a sticky footer, not sure what option this particular theme gives you but the idea is the same with any drupal theme


Add both blocks to a region that you will dedicate for this purpose
if no available region exists you can just create a new one
using custom css on your theme you can make this specific region position: fixed but there are other ways as mentioned by No Sssweat
