Responsive Social Proof Section Using CSS Grid

For laptops with screen heights less than or equal to 800px, I made the grid's height responsive by using vh. I disabled that for taller screens, though, because I didn't want the gap between the header and the testimonials to over-expand.

I opted to use background-image for the stars, because inserting that as an <img> 15 times in the html makes it seem bloated (in my opinion!). Also, they're just decorative elements.
