HTML, CSS, and Javascript (jQuery) for Dynamic Form

This challenge was tougher than I expected. Stylizing the radio buttons was interesting. I ended up using 'display: none' to hide the radio buttons themselves and used the labels associated with each button. It actually ended up looking pretty good, but I am not sure if it was the proper way to do it. The rest of the form was pretty straight forward.

The jQuery was used to allow the user to be presented with another card after rating submission. I ended up using the 'hide()' and 'show()' to exchange out the rating and thank you cards. The functions allowed the cards to be animated for a smoother effect. The only odd thing was I needed to add a 'event.preventDefault()' to prevent the submission from redirecting. My understanding is the function is a way of saying "Hey, I got things handled here, no need to do anything". I do wonder if this is a common thing or if there is a better way to handle this odd scenario.
