3 column preview card component

I appreciate any suggestion to improve my code! Feel free to tell me what I could have done better. The hardest part was to center the card__container and avoid the overflow. In fact i created a media query at a relatively big screen size to avoid the card to go out of screen. When i resize the window the buttons are not in line with each other and i haven't been able to fix it. When the screen gets smaller than 350px the card starts to disappear. How can i fix it? Thank you
