QR Code Component

HTML:

• Every webpage needs a <main> that wraps all of the content, except for <header> and footer>. This is vital for accessibility, as it helps screen readers identify the "main" section of a page. Change .container to a <main>.

• The image has meaning, so it must have proper alt text. Write something short and descriptive, without including words like "image" or "photo". Screen readers start announcing images with "image", so an alt text of "image of qr code" would be read like this: "image, image of qr code". The alt text must also say where it leads(frontendmentor.io).

• Headings should always be in order, so you never start with a <h3>. Change it into a <h1>.

• Change "Scan the QR code" to a <p>.

• .attribution should be a <footer>, and its text must be wrapped in a <p>.

CSS:

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

• Use the style guide to find the correct font-family.

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

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

• Remove the width and height on the card.

• Give the card a max-width of around 20rem 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.

• Since all of the text should be centered, you only need to set text-align: center on the body, and remove it elsewhere. The children will inherit the value.

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