Couldn't quite do it :(

What are you most proud of, and what would you do differently next time?

The non-JS basic CSS is getting easier.

What challenges did you encounter, and how did you overcome them?

However, when making the button clickable, I found it hard to organise the CSS appropriately. In particular:

1. Defining a class to toggle on for the desktop version that I imagine would be a positioned element centred on the button and displaced up by some pixels

2. Defining a class to toggle on for the mobile version to make the social shares on the bottom of the footer. I struggled to find an efficient way, and in particular whether the button should be positioned above everything and the new footer class toggle on / off, or another approach.

What specific areas of your project would you like help with?

Any best practices for the CSS for making the green share div float above the button in desktop mode, but without introducing a complex series of positioned elements that would break the mobile view!
