QR Code

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" section.

• 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 <h4>. 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.

CSS:

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

• I would recommend adding 1rem of padding on the body, to ensure the card doesn't touch the edges on small screens.

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

• max-width on the card should be in rem. Around 20rem will work fine.

• 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.

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

• 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. 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.
