four-card-feature-section

Hello, I did this challenge to practice grid layout (I normally use flex for layout solutions) and get familiar with Tailwind css. I couldn't get the same height of each card component on desktop version- the cards span 2 rows so they look longer than the design. If anyone knows how to adjust this, that would be great. I noticed the top-border colour seems to taper around the rounded corners but the design doesn't do this. If you know how this was done, that would be interesting and helpful too. Any other general feedback is welcome. Thanks
