3-Column preview card using CSS Grid

I use CSS Grid to create the card with a fluid width columns that break into more or less columns as space is available. I used this to make it: grid-template-columns: repeat (auto-fit, minmax (250px, 1fr)).

That works great, but when the columns get smaller the paragraphs of the cards need more lines to fit in the width of the column causing the buttons to go down and, as not all the paragraphs of the cards have the same amount of words, the buttons go down at different points and they look misaligned when that happens.

I tried to solve it by subtracting the padding I gave the paragraphs so that the buttons are aligned again using media query at the points where the buttons are misaligned (at least up to a width greater than 862px). My question is: is there a way to solve this "problem", and if there is, what would be the best way to do it?

Edit: problem solved using absolute position on buttons. Thank you @yudiyoshida for your comment and suggestion.
