3 Column Preview Card Component

I found myself in the problem that the screen sizes indicated that I should create the screens for Mobile: 375px & Desktop: 1440px, but those differentiations in the media queries simpky did not made the job for me, it made some of the cards look too crammed, so I ended up cutting the screens at 672px, which it seems like it worked much better.

I was not able to make the buttons align in every screen size, I'm not particularly sure what to do about this. Screenshot.

Thank you so much!
