This page is the main page of your harmonic-collection. You
could also call it index page because it indexes all your subpages (entries).
You could also call it home or start page because of the location of this index file the browser will automatically open it.
Your start/main/home page DOES NOT COUNT AS AN ENTRY!
To pass this class your collection needs to have (at a minimum):
- functioning links to all entries
- functioning links inside all entries
- 1 startpage like this one
- 10 unique entries with at least 1 .html file per entry
- be responsive: work on mobile phones and desktops
