To make the cards responsive without media queries you can add these two lines of codes to the parent element
display: grid;
grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
Example: We currently have 3 columns (in this case each column has a width of 300px or more). When we shrink the page width we get to a point where all three columns (with 300px width) won't fit to the page, so the coumns will automatically reduce to 2 columns and the rest of the space will be filled with the cards.
This helps us create cool responsive cards without CSS media queris.
