    Hello there 👋. Good job on completing the challenge !

    I have some suggestions about your code that might interest you.

    HTML 📄:

    • Use the <main> tag to wrap all the main content of the page instead of the <div> tag. With this semantic element you can improve the accessibility of your page.
    • Use the <footer> tag to wrap the footer of the page instead of the <div class="attribution">. The <footer> element contains information about the author of the page, the copyright, and other legal information.
    • Always avoid skipping heading levels; Always start from <h1>, followed by <h2>, and so on up to <h6> (<h1>,<h2>,...,<h6>).

    Alt text 📷:

    • The alt attribute should not contain underscores or hyphens, it must be human readable and understandable.
    • The alt attribute should explain the purpose of the image. Uppon scanning the QR code, the user will be redirected to the frontendmentor.io website, so a better alt attribute would be QR code to frontendmentor.io

      If you want to learn more about the alt attribute, you can read this article. 📘.

    CSS 🎨:

    • To center the component in the page, you should use Flexbox or Grid layout. You can read more about centering in CSS here 📘.
    • You should use a CSS reset to remove the default browser styles and make your page look the same in all browsers.

      Popular CSS resets:

      • Normalize.css
      • Reset CSS
      • "My Custom CSS Reset" by JoshWComeau

    I hope you find it useful! 😄 Above all, the solution you submitted is great!

    Happy coding!

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.
