Responsive & Animated Newsletter Sign-Up Form

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

smooth animations (display-property animation now works!)

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

i first tried to set up the success-message container as part of the form-container. My idea was to make a smooth animation from the bigger form-container to the smaller succes-message container. But i failed and couldn't manage to get a smooth width/height animation, because of the paddings of hidden containers. This cost me a lot of time...
