Hi Michelle,
Try adding my-footer-fixed
to the Classes of your Container as such: https://share.getcloudapp.com/o0uRemxn
Remove the margin bottom you set in the Container as well: https://share.getcloudapp.com/d5u9Apeq
Now, add this CSS in Appearance > Customize > Additional CSS:
.gb-container.my-footer-fixed {
position:fixed;
bottom:0;
left:50%;
transform:translateX(-50%);
width:100%;
}
.site-footer{
margin-bottom:54px;
}
Here it is working when I tested it: https://share.getcloudapp.com/6quZrPBZ
Kindly let us know how it goes. 🙂
