    Good job!

    Here are some suggestions:

    HTML:

    • The alt text must also say where it leads(frontendmentor website). Don't include words like "image" or "photo", as screen readers automatically announce it as an image. A good alt text would be "QR code leading to the Frontend Mentor website."

    • Use <p> for the footer text.

    CSS:

    • You don't need to set font-size on html, as 100% is the default value.

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

    • Remove max-width on body.

    • I would move the properties on main to body, and add flex-direction: column and gap: 2rem.

    • Remove all widths and heights in px. We rarely want to set fixed sizes - the content should be able to adapt to all screen sizes.

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

    • 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.

    • As the design doesn't change, there is no need for any media queries. When you do need them, they should be in rem, not px.

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.
