At the start of the challenge I wasn't sure if I should build a second page for the 'thank you' or if I should do it the way I did. I opted for doing it like this because I don't know of a way to get the value of the buttons on another page after the submit.
I also opted for doing the 'selected' effect with JS instead of using buttons and focus because the focus attribute would go off whem clicking elsewhere on the site that wasn't a button.
Also, should I have done the score buttons as actual <button> or is it fine using <ul> <li>?
Sorry for any english misspelling. All feedback is appreciated ! :D
