Responsive solution with flexbox

What are you most proud of, and what would you do differently next time?

It is the first time i use JavaScript in one of these projects, so I am proud of the JS i made

What challenges did you encounter, and how did you overcome them?

my main challenges here were making it so you can only have one button selected, and going on to the next page ONLY if i have already selected an option. I tried a lot of things until I found that the solution was more simple than i thought. Giving too much details would make this very long

What specific areas of your project would you like help with?

I think manipulating specific things of HTML/CSS with JS, but i would probably just look for help online in those topics
