Need help creating a tribute page?

Tell us what’s happening:
I am making a tribute page to Dr. Norman Borlaug. I’m asking a bit simple question. However, I’m confused about the difference between a body and a main tags.

Your code so far

h2{ font-size:20px; } .first-class{ text-align:center; } div{ font-size: 17px; }

A tribute to Dr. Norman Borlaug

The man who saved a billion lives.

Challenge: Build a Tribute Page

Link to the challenge:

An HTML document has 2 parts to it. A <head> and a <body>.
Everything that you see on a webpage is inside the <body> tags. The <main> tag is for the main-content of the webpage , not the header, footer, or sidebar. For example Dr Norman Borlaug’s bio would go in the main tags.
