Well I think it would be better for you to grip the concept of position. Using the style "position : relative" will make your work much better.

If I were you

• I put the three cards in a container div in html and create a inner div for each card as well.
• Then in CSS, I style that div with the feature of "display:flex". They will stand side by side in a row.
• Then with inner div that belonging to each card, I write "position:relative" and then play with like that for every card - top = ..% and left =..%

I hope It is not confusing, When reading or writing it may look so but believe me it is quite easy to do.
