Troubleshooting White Space Issues on Metalsmith Website

Hi. I am working on a website for a friend who is a metalsmith. I have most of the site laid out, but I am seeing a thin strip of white space above the navbar and below the footer. I don't see it in the designer, only on the live site. I can't figure out where it is coming from. I have a backup copy of the site and can share a link. This is my first time using Slack, so I don't know what I am doing... https://linda-weiss-design-e57347ec91ae313f37a9.webflow.io/
