Study very much about flex and grid in css

You can group all the colors and font sizes using the :root selector. This makes it easier to change the styles later.

I noticed you call the p and h4 selectors within each div. Another approach is to target the div, h4, and p directly, as they share the same properties. If you need to exclude a specific div, you can use the CSS :not selector. Alternatively, consider using <section> instead of div for the cards, and <header> instead of the first div.
