product preview (grid/flexbox)

I decided to watch a tutorial before starting this challenge to make sure I'm heading in the right direction with my coding and choices. I still faced many challenges.

The tutorial was by Kevin Powell after seeing a comment by @MattPahuta. Thanks Matt he's very insightful.

I wasn't sure how to get my footer to align to the bottom of the page without un-centering the rest of the content. In previous challenges I was able to sit the footer outside of the body which did the trick. It wouldn't budge from the other content here.
