Responsive Results summary component created with Grid

**I struggled a lot in finding the best sizes of the containers, padding, margin and fonts. Using percentages is difficult at the moment. I got a lot of frustration when on a regular window it was looking ok, but maximizing the browser's window was making me design look ugly in different ways: or too large, or too stretched or the main container broken. This is something I need to learn. **

I watched a video on solution for this project and coded along with the author. Is this a bad practice? I have learnt a lot doing so.
