• It's better in the future to avoid giving your design sizes definite values such as your div with max-width: 320px , It's better to give percentage values to make your design responsive with viewport dimensions. For example, you could assign class .card width: 30%; as you like it to be, So the width of your card will be 30% in relative to class .card width. This helps your design to be flexible growing and shrinking.
• Adding up to the previous point, If you need to assign definite values such as in your font-size, you could check on and use clamp ( ) method ( font-size, width, margins, paddings, etc. ) ,so your design sizes will change according to the viewport dimensions and will be suitable for any device layout. ( Responsive Design )
