All solutions

I couldn't get the <main> element to correctly center horizontally on the screen, it is slightly offset to the right. This is especially noticeable on small screen widths. If anyone knows why this happens I'd be grateful to learn it.

Is my usage of divs ok?

I want to know if my HTML and CSS file structures are following good practices, for example, I used the h3 and p elements for the card title and description, were those good choices or were there better options?
