HTML & CSS Solution (Grid + Flexbox)

Hi! I kept things pretty straightforward with my solution to this project. I used CSS Grid for the page layout and Flexbox for specific sections.

I had a question about the use of container classes. When there are sections on a page that span the entire width (i.e. solid background color or background image), is it good practice to use container classes to keep the content centered on the page, or is there a solution within CSS Grid / Flexbox?

Feedback is welcome!
