    Hi there!

    Here is some feedback - I hope you find it helpful :)

    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."

    • 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 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 all widths and heights in px. We rarely want to give a component a fixed size, as we want 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.

    • Likewise, set font-family on the body, and remove it elsewhere.

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

    • You don't need to set font-style: normal and font-optical-sizing: auto, as both are default values.

    • On the image, add 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. Remove the margin, I'll show you a better way to create the space around the image. You can give it a margin-bottom though.

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

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.
