In some ways this outcome is the opposite of what you were intending. You wanted a Card UI where everything was simple and uniform, but what you end up with is a CSS gallery website filled with baby websites.
A great breakdown from Dave as to why the typical card UI pattern has some inherent issues. Some elements – like making cards all the same height and dealing with responsively collapsing card lists – are now irrelevant thanks to flexbox and CSS grid, but others are inherent to the format. Issues with block links are one potential headache, but you also present information in a slightly bizarre reading format and create a default UI hierarchy that demands a lot of borders. I feel like that last point subtly hits an issue I have with this site's design on the head. Interesting.
