Interactive Rating Challenge

The code probably It's a mess, so sorry for that. First, I couldn't put the classes where It was supposed to be, so I put kinda close. I didn't know how to reduce the size of <submit>, tried several times but didn't manage to do it. So I let how I managed to get. And second, I managed to change the first container to the second container using JavaScript, but couldn't put the number chosen in <span id="score">. The site reads the number, however the textContent don't get the value, tried several times changing with no sucess. I put the lines 24 and 29 of the JavaScript as a commentary.
