Full-Width Footer

Site URL: https://www.amberjainowell.squarespace.com

Still trying to find the CSS to create a full-width footer in York. Anyone? 

Add to Home > Design > Custom CSS

footer#footer {
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
    z-index: 999;
}
.main-content {
    padding-bottom: 5vw;
}

Had problems getting it set correctly initially but figured it out. Just had to mess with that code for a while. Thanks tuanphan, this is the second time you've helped me get something set up properly on my site and I greatly appreciate it!
