News letter signup with Javascript and flexbox

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

I am proud of my flexbox usage as it has really allowed me get better at positioning elements ideally.

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

I feel like the process was relatively smooth.

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

I am just curious if I should be using flexbox as much as I did in the process of making this website.
