here is the link to my pen:
https://codepen.io/Glaurung/pen/OGvaNZ
what is happening is when I click one of the links, no matter where I am, it always brings me to the top of the page. even when I put <a href = "projects">projects</a> it brought me to the top and its id is ‘welcome-section’.

Your CSS is conflicting with your placement…check the three BG-image IDs. If you remove those the links work fine.
