using radio buttons and js

1. This project was a big challenge for me, because first times don´t us the form and label tag (instead button tag), so i have to start completely new.

2. After my second attempt to start the project, i was faced with the challenge of styling the radio buttons so that the numbers 1 - 5 were aligned in the center of the button. I'm proud that I managed to integrate the voting value on the "thank you" card. That caused me a lot of pondering. In addition, the browser automatically removed the spaces before and after the value.....:-(

3. After completing the project, I have already received feedback that some values do not necessarily have to be stored in a variable. Is it best practice for you to only create a variable when it is used several times in the code?

Many thanks in advance for your honest, critical feedback
