3-column preview card component

This was a real challenge. Maybe I could have used grid, but I preferred to do it with flexbox. I ran into a problem when hovering over the buttons, as they increased in size. I solved it by using a solid inner shadow of white color. It also made it very difficult for me to place the button at the bottom of the card. I wanted to do it automatically, but using absolute position I had no choice but to write the distance to the bottom of the card.
