Space Travel Page using Vanilla JS, HTML5 and CCS3 (flexbox)

This project taught me a lot about how to make a page that can be adjusted to the size of the device used by the user. I made several checks with friends to see if it worked in all of them in the same way, I can say that thanks to this I was able to find some errors. and to be able to work on them, I can also say that it is not 100% complete or perfect but I have worked a lot on it, I have been able to work with more confidence with JS than in previous projects.

If you have any feedback to me really appreciate it!!

Thanks a lot.
