It looks like you refactored your repo to have separate folders for milestones 1 and 2. This is good, but some of your milestone-1 links no longer work since the file path is now different.

Milestone 2 is looking mostly good! The link to your name "Ethan Yang" in the navbar currently navigates to index.html. Once you make these two small changes your milestones 1 and 2 will be complete, and I'll close this PR. Nice work!
