First Challenge with Pure HTML and CSS Flexbox

What are you most proud of, and what would you do differently next time?

I think I structured the tags well, but I would love to have done it with frameworks to have components to work with.

What challenges did you encounter, and how did you overcome them?

Main challenge is aligning the elements, as it's been awhile since I've really touched web frontend. Thankfully, obstacles like these are a google search away to solve.

What specific areas of your project would you like help with?

Deciding whether to use padding or margins in adding space. It seems arbitrary but maybe there's a convention that people could suggest.
