This has some of the same issues as previous challenges
- this one is missing the css reset, or you've chosen to change it and broken your solution in the process by limiting the body height to 100vh.
- main also has a limited height when it needs to not have one.
- there are unnecessary css properties throughout like letter spacing 0rem.
- This has incorrect html. These social links would navigate somewhere so that tells you they need to be links not buttons. In this case I'd also expect them to be inside list items in an unordered list.
Hopefully that's helpful alongside previous feedback.
