interactive-rating-component

I found having the hover effect while being able to click the button to change the background color quite difficult and still don't have it working right, I tried doing it with the onmouseover and onmouseleave. Still, then I couldn't get the button to stay clicked when I went to click the submit button, I know my code is very rough, I have only recently learnt DOM javascript and this was my first time putting it into a project, any. All feedback is absolutely welcomed, and offering alternate and better solutions, please feel free.

Thanks!
