Fixed footer below and cart in menu

Hello I have 2 questions.
1. How to leave the footer fixed below, in this image (https://imgur.com/a/VyoYSq6) I sent according to the page if there is little content it goes up, leaving space in the arms right after it.

2. How can I show the cart at the end of the menu? such as the search button (magnifying glass).

Thanks
