Four Card Feature Section using TailwindCSS

I never really use CSS Grid for layouts. Generally, I've been pretty happy with trying to negotiate flexbox for creating my layouts. This time I wanted to challenge myself to use grid and flexbox to create the layout from the design. Trying to center the outer card columns vertically was difficult but after I practiced grid by playing Mastery Games - Grid Critters, I was able to transfer the knowledge to Tailwind utility classes and center the outer columns.
