Next Challenge, Still Learning...

Dear All,

Here is my next challenge, still an easy one, but full of real challenges to me. The biggest one here is that I was starting to use percentages instead of fixed sizes, like width or height because I have been warned about avoiding the latter. However, I noticed that here, it worked better to add a fixed width to keep it responsive. Why is that? Is there a consesus on when to use percentage and when adding specified amounts is preferred?

Thank you for checking out,

Cheers to you all,

Dalma
