Well done! To imitate the design, the font should be a shade lighter but your version looks fine. Also, many <div>
elements could be replaced with more semantic elements such as article and section. Your sass is very clean and easy to read.
For the tooltip, I made it the last element of the card and toggled it with a data attribute.
P.S. : Never gonna give you up, Never gonna let you down, Never gonna run around and desert you
