Off-Platform-Project: Tea Cozy

Hi everyone,
I’ve came up with a solution to make the Tea Cozy challenge to make website responsive on different viewports. I took me a while but I learned a lot from the challenge. It’s difficult when you’re coding on your own to know if you’re doing it the right way. Any advice on how I could improve the code would be most welcome
