    HTML:

    • Remove the .attribution if you are not going to include it.

    • 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. Change .container into 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 website).

    • Never have text in divs alone. "Improve your" is a <h2>, and "Scan the QR code" is a <p>. You don't need to wrap either in a <div>, so remove those 2 divs.

    CSS:

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

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

    • You don't need the .center class so I would remove it. To center the card horizontally and vertically, use Flexbox on the body:

    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    min-height: 100svh;
    
    • Remove all properties on .container.

    • Remove all widths, as well as min-height and max-height on the card.

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

    • I would use rem instead of em on font-size.

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

    • To create the space between the image and the edge of the card, set padding on all 4 sides of the card:padding: 16px;.

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

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
