Responsive age calculator with jquery

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

I'm really proud to do this one, at first I tought it would be way easier than it was.

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

The first challenge was to calculate the age, the days and months, and code it! It was done by trying and getting it wrong and trying again. The responsive was a issue as well, I suffered a little bit to put the purple circle at the middle and the line trought it, actually I don't think I did it in the best way.

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

If you can see my code and point how I can be cleaner, I would really appreciate any feedback. Thank you!
