Responsive Landing Page CSS grid

I did this project to learn about grid and how to use it. I really have had trouble understanding responsive design and more fundamentally how a dev structures their CSS code. I followed one of Kevin Powells videos and it was very helpful, that along with comparing my code with his repository gave me a lot of insight into how a developer structures their HTML and CSS. I had some working knowledge of flexbox and have been getting along ok with that. Knowing grid however is a game changer. Utilizing both of these display options will make responsive design so much easier in the future!
