Footer disappears on my main page when i use position:fixed on BRODWAY Project

Hi, will anybody help me please, I try to fix my footer regardless of scrolling but when I add: position: fixed on CSS file, it disappears… I thought about using z-index but couldn’t figure out how!
here is my project code: https://codepen.io/oumaimafisaoui/pen/zYqogEN?editors=1100
thank you!

Hello, welcome to the forums.

Try this:

 position: fixed;
 bottom: 0;
 width: 100%;
