Responsive using css pure and media queries.

Couldn't figure out how to the half circles on the bottom of each divition. Also, as something I learned was, that even thought something breaks (in this case my sass), it's essential to always be organised when writing code. Honestly, by the end I was somewhat confused because of my lack of organization. So I am happy for this project as it taught me this. If you have any feedback will be glad to hear about it :)
