    Hello there 👋. Congratulations on successfully completing the challenge! 🎉

    • I have other recommendations regarding your code that I believe will be of great interest to you.

    HTML 🏷️:

    • This solution generates accessibility error reports, "All page content should be contained by landmarks" is due to non-semantic markup, which lack landmark for a webpage

    • So fix it by replacing the <div class="container"> element with the semantic element <main> in your index.html file to improve accessibility and organization of your page.

    • What is meant by landmark ?, They used to define major sections of your page instead of relying on generic elements like <div> or <span>

    • They convey the structure of your page. For example, the <main> element should include all content directly related to the page's main idea, so there should only be one per page

    HEADINGS ⚠️:


    • And, this solution has also generated accessibility error report due to lack of level-one heading <h1>

    • Every site must want at least one h1 element identifying and describing the main content of the page.

    • An h1 heading provides an important navigation point for users of assistive technologies, allowing them to easily find the main content of the page.

    • So we want to add a level-one heading to improve accessibility by reading aloud the heading by screen readers, you can achieve this by adding a sr-only class to hide it from visual users (it will be useful for visually impaired users)

    iMAGES 📸:

    • Since this component involves scanning the QR code, the image is not a decoration, so it must have an alt attribute.

    • The alt attribute should explain the purpose of the image.

    • E.g. alt="QR code to frontendmentor.io"

    .

    I hope you find this helpful 😄 Above all, the solution you submitted is great !

    Happy coding!

    Hello there 🙋‍♂️! Great job on this challenge 🎉!

    I think it's awesome that you're asking questions about how to learn more efficiently. Wanting to learn how to learn better is already a great mindset to have.

    When learning a new concept, I like to watch a video tutorial explaining the concepts. I then write down any questions that I have and see if a rewatch helps me answer those questions. Otherwise, I then try to read any official documentation on the topic if it exists.

    Looking at the HTML and Accessibility reports that Frontend Mentor gives is a good starting point if you want to improve your knowledge and skills.

    I have a few links below that will help you resolve those errors.

    Accessibility ♿️:

    • Document should have one main landmark. Landmarks help accessibility tools navigate your page.
    • Alt text. Alt text in images allow tools like screen readers to properly convey the content of your site.
    • Level 1 heading. For accessibility reasons, pages should always have an <h1> tag.

    HTML Validation Report 🔨:

    • Add some alt-text to the <img> tag describing what the image is or what it is for.
    • You may have wanted to use an <h1> tag instead of just <h>.

    I hope this helps! ✌️

    I look forward to seeing more of your work in the future! 😄

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.
