Responsive Component with CSS Grid

Hello.

So this was me practicing my CSS Grid muscles😁...I went a bit extra to design the component at three breakpoints instead of two, manipulating the layout accordingly, thereby getting more practice. I'm still a newbie so I will really appreciate your constructive criticism of my code and your opinion(s) on what I could have done better, generally or specifically. Thank you very much.

@kxnzx and @beowulf1958...I'm practicing the mobile-first workflow as well and so far, so good.
