HTML, CSS, Responsive design

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

I did the desktop design of the page very fast, but I got stuck on the responsive mobile part. I had to experiment with styles in order to make the page responsive.

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

Setting styles for responsive mobile version was a bit challenging but I managed to make a mobile version.
