Advice Generator | React + API

Hi guys! This was a fun challenge that took me 80min to finish, I have a couple questions and would appreciate answers:

1 - Is there a better way to change images according to devise size (Desktop or Mobile) 2 - Sometimes the webapp renders twice the first time it loads which results in two subsequent api calls that display two advices in a row. How can I avoid this additional render?

Feel free to suggest additional improvement Thank you
