User story

A user can quickly eyeball pages on the Making Sense of Web3 site by looking at the table of contents (ToC) on the left-hand sidebar. He can also quickly navigate to different pages by clicking on their titles in the ToC and see where he's currently at thanks to highlighting of the current page.

Inspiration

Tailwind page:

Acceptance

• ToC on the left-hand side that lists all the pages, reflecting the tree of routes/pages
• ToC should always be visible (doesn't hide on scrolling)
• the title of the current page should be highlighted
