FAQ Acording Card (CSS-JS) 💚

Hello community, this project was complicated in the Js part because I feel that the code is not quite right, but the functionality is correct, and as for the design, if you can give me suggestions of what I can improve in my Css, I would appreciate it very much, and also my Js code, and html, I think it is correct and semantic, I did not use the details or summary tags, because I wanted a more personal design. And well as always you can tell me anything about my project and Happy coding. 🧡
