QR code components using CSS Flexbox

HTML:

• Do not use "image" or "photo" in the alt text. Screen readers start announcing images with "image", so an alt text of "QR image" would be read like this: "image, QR image". The alt text must also say where it leads(frontendmentor.io).

CSS:

• It's good practice to include a CSS Reset at the top.

• Add around 1rem of padding on the body, so the card doesn't touch the edges on small screens.

• Remove width on body, and width and height on the card and the image.

• On the body, change height to min-height - this way, the content will not get cut off if it grows beneath the viewport.

• Add a max-width of around 20rem on the card, to prevent it from getting too wide on larger screens.

• font-size must never be in px. This is a big accessibility issue, as it prevents the font size from scaling with the user's default setting in the browser. Use rem instead.

• On the image, add display: block and max-width: 100% - the max-width prevents it from overflowing its container.
