Nice work! The only advice I’d give is don’t use patterns like div.parentElement.parentElement.foo() It’s inflexible and will break if you ever make dom changes. Use the .closest() selector instead. It’s like a reverse .querySelector (.closest selects ancestors, .querySelector selects descendents) which means you’ll have more specific code.
