  Hello, good job.

  Here are some suggestions:

  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 a page's "main" content. Wrap the card in a <main>.

  • The alt text should be written naturally, without using - between the words. 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(the frontendmentor website). A good alt text would be "QR code leading to the Frontend Mentor website."

  • Headings should always be in order, so you never start with a <h3>. I would change the heading to a <h2> - a page should only have one <h1>, reserved for the main heading. As this is a card heading, it would likely not be the main heading on a page with several components.

  • Change .attribution to a <footer>, and use <p> for the text inside.

  CSS:

  • Including a CSS Reset at the top is good practice.

  • Move font-family to body.

  • I recommend adding a bit of padding, for example 16px, on the body, to ensure the card doesn't touch the edges on small screens.

  • On the body, change height to min-height: 100svh - this way, the content will not get cut off if it grows beneath the viewport. Remove width, as the body by default takes up the full width.

  • Remove all widths and heights in px. We rarely want to give a component a fixed size, as we need it to grow and shrink according to the screen size.

  • We do want to limit the width of the card, so it doesn't get too wide on larger screens. To solve this issue, give the card a max-width of around 20rem.

  • 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.

  • Paragraphs have a default value of font-weight: 400, so there is no need to declare it.

  • On the image, add display: block, height: auto and max-width: 100% - the max-width prevents it from overflowing its container. Without this, an image would overflow if its intrinsic size is wider than the container. max-width: 100% makes the image shrink to fit inside its container.
