Responsive Calculator App using CSS Grid

Hello Fellow Developers, This is my solution for calculator-app challenge. It was very enlightening to work on this challenge.

I learnt how to add multiple color theme to an interface and allow users to change it using a switch, also about prefers-color-theme

The prefers-color-theme media feature is something totally alien to me, it took me a while to wrap my head around it but now I know it is used to adapt the colors to the user's browser theme settings.

Do check it out and give feedback, I'd really appreciate it.
