Tribute Page - Build a Tribute Page - Center Image Inside of Parent

Tell us what’s happening:
How do I center the image inside of the parent? I’ve tried using display: flex, align-items: center, and justify-content: center, but nothing is working.

Challenge: Tribute Page - Build a Tribute Page

Link to the challenge:

Don’t use pixels as your min width. This will throw off centering on smaller screens.
You can use a relative unit value like % or rem for eg.
