Responsive (mobile and Desktop), using FlexBox and Grid.

For this project, I decided to try 'display=grid' in conjunction with 'display=flex'. I could've used 'display=grid' in the 'section=creations' instead of creating a new button for the mobile version, but it only occurred to me after the fact 😅, so I decided to leave it as it is but to use it on the footer section. Feel free to leave your feedback, I'm giving my first steps here 😁, and any help will be much appreciated. Happy coding everyone.
