Hi, I found this project a bit harder when it comes to the responsive design, even though I made the media query for the mobile view, I think is not yet adequate. I appreciate any suggestions or recommendations about it.

Question: When doing this kind of projects, do I need to set width/height for the elements according to the media queries or should I set a fixed value first and then modify it through each media query?

Thanks!
