Interactive rating card using only vanilla html/css/js

Hey there!

That is my attempt to make an interactive rating card which I think I did it! I'm pretty happy with the result. Although I feel a little bit unsure about the state management I did in javascript and the approach of hiding and revealing sections using Element#attributeToggle method.

Also I modified a little bit the user experience so I did the button disabled and chose that gray color so it might look a little bit different in first look. I think it's a little bit better that the button gets enabled after user pick any number. Also I swapped hover and selected colors because to my mind it makes more sense when selected item has the primary color and hover just a little bit offset-ed color than original

Feel free to criticize my work and suggest to me some small or huge changes in order to make my code better. Thank you in advance!
