Responsive intro page using html/css/vanilla javascript

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

Proud that i'm continuing to improve on being able to understand JavaScript more, though being able to write it from scratch is still tough.

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

Lots of difficulty with the JavaScript validation segment of the challenge, even modifying code segments to suit my implementation is difficult at this stage. Hopefully with practice i'll improve here.
