Unit Converter Feedback

Hello fellow campers, my business here is to ask feedback on a Unit Converter that I did a while back (I finished it at the end of November). I’m pretty sure that some of the colors and the interface might need some work but I’m not quite sure how to go about it. This is just a project that I wanted to do and not a FCC Project so yeah. I’m thinking of perhaps making another version of this Unit Converter that only uses Text Input (I learned about it December). Thank you and I hope to hear back from you all.

Which project did you complete?I mean in which section of freecodecamp curriculum

This isn’t any of the Free Code Cam projects; it’s my personal project. But I’m quite sure that if this was a project that it would be HTML/CSS/JS project since I used all of those elements in my Converter.
