Using Hover to interactive the buttons

If you want to make your card responsive with ease you can use this technique:

.card {
width: 90%;
max-width: 37.5rem;
}

On the smaller screens card will be 90% of the parent (here body), but as soon as the card will be 37.5rem (600px) it will lock with this size.

Also to put the card in the center I advise you to use this code snippet:

.container {
display: grid;
place-items: center;
}

Good job and keep going 😁😊😉

Your solution can be improved using semantic elements like section, header and main. The code seems good and readable. But The layout of the page breaks in small screen sizes. You should look at it and fix your media query styles.
