I tried using the Chrome inspector, some changes were working but not in live. So I need a css ninja to help me fix those change. Plus a jQuery toggle function on a part of an form in those products (I using kadence theme and woocommer products add on). Once the change will be done, I need to translate those products so the changes will be cloned too.

I put a google slides link below + the url of the website above. I need someone avalaible now. It's a one hour job or so.
Thanks in advance
