Crowdfunding page with animations, form validation and modals

This was really challenging! I tried to do more than what the challenge required, adding an animation for the progress bar, form validation, a tooltip showing how much the total donation increases, the and making impossible to donate when the goal is reached. Being a beginner, I'm sure there is room for improvement. Any tip is appreciated.

Also: I had problem displaying the Commissioner font on Firefox. I solved it using @font-face. Anybody else had the same issue? Just curious.
