Responsive Three Column Layout

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

This is my best project so far. I would not second guess myself next time.

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

Turns out there's something called leading space which makes it close to impossible to create a perfect layout without using hacky stuff. So I stopped second guessing myself and made the layout as close as possible.

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

Any help is highly appreciated.
