Responsive NFT card component using CSS Flexbox

Is the CSS I used for my footer not to overflow, ok? Or should I do something else? I struggle with it a lot to make it not overflow, so I am curious if there is a better way or if I finally cracked it. 🥹

footer {
    background-color: hsl(216, 50%, 16%);
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 2em;
}

footer p {
    font-weight: 400;
    font-size: 1.1rem;
    color: hsl(0, 0%, 100%, 0.5);
}

(hopefully the code formatting works here 😅)
